1. Martensitic Transformations in Steels : A 3D Phase-field Study
Sammanfattning : Martensite is considered to be the backbone of the high strength of many commercial steels. Martensite is formed by a rapid diffusionless phase transformation, which has been the subject of extensive research studies for more than a century. LÄS MER
2. Finite element simulation of transformation plasticity in martensitic transformation
Sammanfattning : This study is concerned with the simulation of transformation plasticity in martensitic transformation. In the first paper the concept of a transformation plasticity strain is introduced from a phenomenological point of view. LÄS MER
3. Laser-induced phase transformations in microalloyed steels
Sammanfattning : The application of thermal cycles below melting temperature can induce solid-to-solid phase transformation in steels, which is the transition between different crystalline structures of the same compound. There are many types of crystalline structures in steels produced, depending on the characteristics of the applied thermal cycle. LÄS MER
4. Deformation and martensitic phase transformation in stainless steels
Sammanfattning : The use of high-energy synchrotron x-rays which has enabled three- dimensional structural characterization from the nano- to the macroscopic scale, and now to the meso-scale, such as individual grains and dislocation structures, is a major scientific advance. This is the first technique with sufficient spatial resolution and penetration power to probe the local structure embedded deep within the material. LÄS MER
