1. Modeling the Microstructure Evolution During and After Hot Working in Martensitic Steel
Sammanfattning : In this study, the goal is to predict the microstructure evolution during and after the hot working of a martensitic stainless steel with 13% chromium using a physically-based model in the form of a MATLAB toolbox. This model is based on dislocation density theory and consists of coupled sets of evolution equations for dislocation, vacancies, recovery, recrystallization, and grain growth. LÄS MER
2. On the Origin and Distributions of the Inclusions in Production-scale ESR and PESR Remelted Ingots and Materials from Different Ingot Sizes and Solidification Structures
Sammanfattning : The study was carried out with the aim to evaluate the origin, morphology, and distribution of the non-metallic inclusions (NMI) in electro-slag remelted (ESR) steels and in electro-slag remelted steels using a pressured controlled inert atmosphere (PESR). In addition to the NMI studies, the solidification structure in different ingot sizes were studied in order to define the influence of the solidification on the NMI characteristics. LÄS MER
