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.
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 in order to make it easier for designers to minimize the risks for high-temperature corrosion when designing components/systems for high operating temperatures.
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
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.
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.
