1. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : 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
University essay from KTH/MaterialvetenskapAbstract : 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. Effect of alloying elements on the hardenability of PM steels
University essay from Malmö universitet/Teknik och samhälleAbstract : In an effort to broaden the use of powder metallurgy components to high load applications it is necessary to increase the mechanical properties. One way of doing so is to optimize the chemical composition and increase the hardenability. In this report a hardenability evaluation is performed on Astaloy™ CrA (Fe+1,8wt.%Cr) with 0,6 wt.

4. Low Temperature Creep/Relaxation Behaviour of PM Steels under Static Load
University essay from Chalmers tekniska högskola/Institutionen för material- och tillverkningsteknikAbstract : Powder metallurgy (PM) is one of the metal forming techniques to manufacture structural components in high volumes. Almost 70% of the PM steels produced are used in automotive applications. READ MORE

5. Three-dimensional investigation of non-metallic inclusions during powder metallurgy production
University essay from KTH/MaterialvetenskapAbstract : 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. READ MORE
