1. Study of precipitation in martensitic Fe-C-Cr alloys during tempering : Experiments and modelling
Sammanfattning : Understanding the precipitation reaction is very important since precipitation hardening is one of the most effective strengthening mechanisms in metallic alloys. In martensitic steels, a tempering heat treatment is often performed. LÄS MER
2. Influence of thermal loading on mechanical properties of railway wheel steels
Sammanfattning : Material integrity and properties of wheels are critical in railway traffic, as wheels fulfil the important function of transferring load and traction from the vehicle to the rail track. Steels with a pearlitic microstructure are commonly used for wheels due to their height strength, low cost and good wear properties. LÄS MER
3. Development of Structural Steels for Powder Bed Fusion - Laser Beam
Sammanfattning : Over the past decade, powder bed fusion – laser beam (PBF-LB) has attracted noticeable attention from both academia and industry. However, there remains a scarcity of approved material for the process, as fewer than 40 alloys are commercially available. LÄS MER
4. Effect of austenitising temperature and cooling rate on microstructures of hot-work tool steels
Sammanfattning : The average size of hot-work tools has gradually increased over the past years.This affects the effective temperature cycle tools experience during hardening,as large dimensions prevent uniform and rapid cooling, and thereby the resulting microstructures and properties. LÄS MER
