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 analysed through crack inspection, microscopy, metallography and tensile testing and how heat treatment can be used to modify the material properties
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, aluminium 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.
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.
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).
Steel and heat treatment and forging
This course is best suited for people working with steel and steel components such as e.g. axles, beams and gears. The course discusses the key factors during the steel manufacturing process and the crucial importance of correct heat treatment of the steel components.
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.
Corrosion
By better understanding the underlying mechanism of corrosion we are more likely to avoid bad design choices for metallic parts. The course aims to give an introduction to common types of corrosion, such as general, galvanic and high temperature corrosion and to go through important material- and environmental parameters which affects the amount of corrosion.
Introduction to Additive manufacturing of metals
The course is an introduction metal additive manufacturing. The training covers the basics of the techniques and processes (e.g. SLM, EBM, Binder jetting…). The advantages and limitation of the techniques, as well materials used, are discussed. Moreover, some applications and examples are given.
General knowledge of plastic materials
Introduction (1/2 day)
Thermoplastics (1/2 day)
Polymers Elastomers (1/2 day)
Thermosets (1/2 day)
Materials Technology – Electronic Assemblies and Failure Analysis
The number of Electronic Assemblies are constantly increasing in the vehicle industry. This course will focus on basic understanding of Printed Circuit boards, the components mounted on them and typical failure modes. It will also give information on what to consider when purchasing or designing an electronic assembly. The courses will contain information about what type of failure analysis that can be performed at Volvo Materials Technology.
Learn the basics about Electronic Assemblies – Printed Circuit boards, their surface finish and the components mounted on them.
Have knowledge about how the Electronic Assemblies are produced.
Basic understanding of what to consider when designing an Electronic assembly from a material and mechanical perspective.
Awareness of what type of stresses they can be exposed to during their lifetime in a truck environment and what typical failure modes they have.
Have knowledge of what type of non-destructive and destructive test that can be performed on the Electronic Assembly and what type of knowledge and equipment that the Volvo Materials Technology department can support with.
