2. Formation of Bainite in Steels
Sammanfattning : A systematic survey of morphology of bainite and proeutectoid ferrite was carried out in order to validate some old thoughts of bainite transformation mechanism. It is confirmed that there is no morphological evidence supporting a sharp change neither between Widmanstätten ferrite and the ferritic component of upper bainite, nor between upper and lower bainite.

3. Defects in Austenitic Steels and Hard Metals - A DFT-based Study
Sammanfattning : Materials are never 100% pure due to the limitation of purification method or manufacturing process. Nor are they perfect, especially under deformation. The present work aims to explore different roles played by the defects in austenitic steels and hard metals. LÄS MER
4. On the hot crack formation during solidification of iron-base alloys
Sammanfattning : Hot cracking during solidification is a severe problem inmany casting processes, for example in continuous casting.Combinations of low strength and low ductility of the materialat high temperatures and applied tensile stress can cause hotcracking. LÄS MER
5. Microstructural Characterization of Expanded Austenite in 304L and 904L Austenitic Stainless Steels
Sammanfattning : Austenitic stainless steels are among the most used materials in modern industry, mainly because of their superior corrosion resistance. However, low hardness and poor tribological properties often restrict their applicability. LÄS MER
