Materials Technology Courses

Do you have difficulties in selecting materials for your components? Or do you simply want to improve your material knowledge?
Then, the courses at Volvo Materials Technology are something for you.

There are tons of different materials, surface treatments, and joining methods to choose from. As a design engineer, it can be difficult to know which choices that are best suited for the intended component. This is why Volvo Materials Technology has developed a variety of courses especially adjusted to help design engineers, but also purchasers and test engineers in contact with materials. The courses are held each year.

The experts of the department work with material related issues every day. All have many years of experience within applied materials technology for Volvo applications. They therefore know which problems to look out for, and have adjusted the course contents in such manner. Thus, these events are excellent opportunities to learn how to avoid easily made mistakes and at the same time become a material expert of yourself.

Courses in Materials Technology are held regularly. We can also provide courses at any time of year upon request.

The Basic Materials Technology and Failure Analysis
Provides a fundamental understanding of terminology and mechanisms within the field of metallic materials. Naturally, its scope is the material used within the vehicle industry. Areas of focus will be on chemistry, phase transformations and hardening mechanisms and its effect on material properties. The course also treats failure analysis in detail with actual failure investigations performed at Volvo Materials Technology as a base for discussion. Moreover, a practical demonstration will show how materials and failed components are analyzed through crack inspection, microscopy, metallography and tensile testing and how heat treatment can be used to modify the material properties

Thermal Spraying
This course is best suited for people working with surface treatments or trying to solve surface issues (wear, heat insulation, electrical insulation / conductivity, remanufacturing, etc.).  The course discusses thermal spraying processes and the resulting types of coating. Several examples of practical applications, some linked to the automotive sector, are presented. Basic information with regards to coating design is given as well as some simple economics. 

Cast Materials
This course is best suited for people working with cast components such as cylinder blocks and heads, brackets, manifolds, casings etc. The course discusses processes, design, properties, and microstructure. A focus is the understanding of how the mechanical properties are affected by the casting method, heat treatment, defects and microstructure. Casting design, casting specifications, non-destructive testing methods and after-treatments are included. The course discusses our common cast materials such as grey iron, Compacted Graphite Iron (CGI), nodular iron, aluminum and magnesium. Different casting methods as sand casting, gravity die casting, high pressure die casting and rheo casting are explained. 

Screw Joints
In a truck there are over 2000 screw joints and the use of screws will be an important joining technology also in the foreseeable future. There are currently two courses that give an introduction to screw joint technology. Courses targeted at specific groups (Ex. Purchase, Assembly, Maintenance) can be held upon request. It is also possible that the course is held at your location alternatively through video link.

Screw Joints – Basic
This course gives an introduction to screw joint technology.
Basic features such as strength classes and static strength is covered. Influence of friction and settlements on clamping forces are shown. The importance of joint stiffness consideration for fatigue strength is discussed together with differently assembly methods. Some practical examples are presented together with rules of thumb for screw joint design.
This course is available in English and Swedish.

Screw Joints – Calculations
This course is best suited for designers who want to learn more about basic calculations and measurements of screw joints. It includes basic calculation methods for static and dynamic strength, clamping forces and some statistics.
This course is available in English only.

Steel, forging and heat treatment
This course is best suited for people working with steel and wrought steel components such as e.g. axles, beams and gears. The course discusses the key factors during the steel manufacturing process, the critical factors during forging of steel blanks and the crucial importance of correct heat treatment of the steel components.

Steel
The first part of the course gives an introduction to the material steel, factors that decide its quality, developments and price sensitivity.

Forging
The second part gives a definition about the forging process, its types, material properties under forging and defects.

Heat Treatment
Steel is one of the most widely used material thanks to good mechanical properties & interesting physical properties for a relatively low cost. Furthermore, steel is a versatile material where properties can be significantly affected by both chemical composition and heat treatments. Basics for heat treatments are discussed, and different heat treatments are explained and compared with focus on typical Volvo group components. Furthermore, the importance of correctly performed heat treatment is underlined with examples of failures related to poor heat treatment.   

Surface Technology
Tribological questions do not always have easy answers. For instance, switching to a harder material might sometimes increase the damage of wear rather than reducing the damage. This course is developed to give a basic understanding of surfaces and their properties during friction and wear. How can, for instance, wear and friction problems be prevented? The course will discuss different types a war and how various surface coatings can reduce such problems. Furthermore, a presentation of the process for a number of common surface treatments is also included in the course.

High-Temperature Corrosion
Several important components/systems (e.g. turbo, injection system, exhaust after treatment system, exhaust manifold) in our products are exposed to high temperatures, which in combination with a harsh environment (e.g. urea) may lead to extensive high-temperature corrosion that in turn leads to failure. The aim of this course is to give a general understanding of high-temperature corrosion when designing components/systems for high operation temperatures.

Sintered Steels / Powder metallurgy
Sintered steels are produced to net shape without machining and the number of sintered products in the vehicle industry is constantly increasing. The course discusses manufacturing processes, properties, design issues and applications regarding sintered steels. Moreover, the course will also bring up other powder metallurgical manufacturing methods, such as metal injection moulding (MIM), hot isostatic pressing (HIP) and additive manufacturing (AM).  

Corrosion – Focus on engine components
The aim of this course is to give a general understanding of corrosion and corrosion protection:

  • Why do metals corrode?
  • Corrosion mechanism
  • Different types of corrosion
  • Corrosion protection

The course has a focus on engine components, including air inlet and exhaust parts.

Welding and Brazing Methods
The course gives a general description of common welding- and brazing methods of components and base materials encountered within AB Volvo, For welding, arc welding methods (e.g. MIG/MAG, TIG), high energy beam welding (e.g. laser welding), electrical resistance welding methods (e.g. spot welding, flash welding, seam welding), pressure welding (e.g. friction welding) and special welding methods such as arc stud welding is discussed. For brazing, methods involving local heating (e.g. flame- and induction brazing) and furnace brazing methods (e.g. vacuum furnace brazing) are discussed. 

Areas of focus are how welding affects the properties and microstructures of the different base materials such as steel, stainless steel and aluminum alloys. Special focus is given to common weld defects encountered for the different welding methods and base materials (e.g. solidification- and cold cracks in steel, corrosion resistance of stainless steel and porosity issues in welding aluminum). Examples of failed welded- and brazed joints are reviewed. Current Volvo standards for welding and brazing are discussed. Design and stress calculations of welded and brazed structures are only covered briefly.

The course discusses welding and brazing in general of the most common components and base materials. Areas of focus are different weld and braze methods, how welding affects the properties of the base materials (i.e. microstructure, , defects in welds and Volvo standards for welding. Design and stress calculation of welded or brazed structures is only covered briefly. 

Residual stresses – Introduction
This course serves as an introduction for the residual stresses in materials and the used methods of measurements. The course reviews the origin of residual stress and how it affects the component life. Also, the course presents the X-Ray diffraction method as a standard way and a widely used method of residual stress measurements.
