1. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

2. In-situ Reduction by Incorporating H2 Filled Hollow Glass Microspheres in PM HIP Capsules
Master-uppsats, KTH/MaterialvetenskapSammanfattning : For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB).

3. Three-dimensional investigation of non-metallic inclusions during powder metallurgy production
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Due to growing demands for steel powder properties and continuous evolution of the powder metallurgy (PM) production it is necessary to apply new investigation technics and research applications for quality investigation of the PM products. In addition, it is important to be able to predict the probable maximum size of inclusions. LÄS MER
4. Study of Total Oxygen Content and Oxide composition Formed During Water Atomization of Steel Powders due to Manganese Variation.
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Powder metallurgy (PM) is a technology used to manufacture near net shape components for an increasing number of applications like automobile components, aircraft components, cutting tools, refractory, household appliances, etc. The general PM process comprises of Powder manufacturing/powder tailoring, Compacting, and Sintering.
