11. Deformation Behaviour, Microstructure and Texture Evolution of CP Ti Deformed at Elevated Temperatures
Sammanfattning : In the present work, deformation behavior, texture and microstructure evolution of commercially pure titanium (CP Ti) are investigated by electron backscattered diffraction (EBSD) after compression tests at elevated temperatures. By analysing work hardening rate vs. flow stress, the deformation behaviour can be divided into three groups, viz. LÄS MER
12. High temperature performance of materials for future power plants
Sammanfattning : Increasing energy demand leads to two crucial problems for the whole society. One is the economic cost and the other is the pollution of the environment, especially CO2 emissions. Despite efforts to adopt renewable energy sources, fossil fuels will continue to dominate. LÄS MER
13. Activated Recrystallization of Non-Sag Tungsten Wire
Sammanfattning : The objective of the present investigation was to explore the mechanism of activated recrystallization of heavily drawn doped (non-sag) tungsten wire material. The recrystallization can be induced at low temperatures by the presence of some metals, such as palladium, nickel, iron and others, on the wire surface, which is important as it can seriously deteriorate the mechanical properties of non-sag tungsten wires, when the wires serve as reinforcement material in metal matrix composites.
