1. A Ni3Al-alloy and its Composites as Potential Wear Resistant Materials for Advanced Applications
Sammanfattning : The Ni3Al-based intermetallic alloys as engineering materials in service, they may be subjected to a wear environment of some sort. Hence, it is technologically important to understand the tribological response and to determine methodologies to improve wear resistance of these advanced materials. LÄS MER
2. Micro-scale studies of wear
Sammanfattning : The development of materials for tribological components is constantly striving to more sophisticated properties, specialised for specific applications. This progress requires and depends to a large extent on a parallel development of the theoretical knowledge of wear and on development of the experimental tools for investigating wear in the research lab as well as in the field.

3. High Performance Manufacture of Sintered Steel – Critical Aspects of Tooling Performance and Sintered Microstructure
Sammanfattning : Steel is the dominant material for the production of structural parts. By means of powder metallurgy (PM) processing, manufacturers have been able to manufacture steel parts with appreciable dimensional accuracy and desirable mechanical properties. LÄS MER
4. High Temperature Friction and Wear in Press Hardening
Sammanfattning : In the automotive industry, press hardening is usually employed to produce safety orstructural components from advanced high–strength steels. This hot forming process, andthermomechanical forming processes in general, is highly dependent on friction betweentool and workpiece as friction affects and controls the deformation of the workpiece.

5. Modelling and Simulation of Train-Track Interaction including Wear Prediction
Sammanfattning : Many problems in railway traffic arise as a result of the dynamic interaction between rolling trains and tracks. The problems include both instantaneous effects due to induced vibrations of track and vehicle, and more long-term processes of a detrimental nature. LÄS MER
