Study of White Etching Layer in Rail Steel R260Mn by Thermo-Mechanical Simulation

Railway transport plays a vital role in a country’s economic growth. Derailments result in loss of life, damage to rolling stock, service disruptions and harm the environment leading to the decrease in economic growth of a country. Improving train operating safety has been a high priority of the rail industry and the government. Train accidents...

Dislocation networks in precipitation hardened aluminium alloys during plastic deformation: The effects of dislocations on the anelastic behaviour and the evolution of dislocation networks in an AA7075 aluminium alloy.

The effects of precipitates in the microstructure of an AA7075 aluminium alloy on: the dislocation behaviour, dislocation structure and dislocation structure evolution during plastic deformation were investigated using the physical yield criterion model by van Liempt and Sietsma. The model was in fact applied for the first time to aluminium and...

Tungsten Recrystallization Behavior Under Steady and Transient Hydrogen Plasma Loading

Because of its extraordinary material properties, like its high melting point and thermal stress resistance, low erosion and swelling rate, and high radiation damage resistance, highly deformed pure tungsten has been chosen as the plasma facing surface material for the ITER reactor divertor. The study of tungsten’s recrystallization behavior and...

Investigation of the relation between grinding process parameters and created curvature and roughness of the pushbelt element saddle surface for optimizing the pushbelt element-ring contact in Continuously Variable Transmissions

In a Continuously Variable Transmission (CVT), the pushbelt is the torque transmitting part consisting of around 400 steel elements which are held together by steel ring packs. Relatively high friction losses of the operating pushbelt are associated with the element saddle surface on which the steel rings are lying. The...
