1. Processing Methods for Reaching Full Density Powder Metallurgical Materials
Sammanfattning : Powder metallurgy (PM) is one of the most cost effective methods for manufacturing structural components with complex shapes. Utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. LÄS MER
2. Influence of Segregants on Creep Fracture in Powder Metallurgical Martensitic Stainless Steel
Sammanfattning : This thesis deals with the behaviour of segregants in Powder Metallurgical (PM) 10%Cr steel and their impact on creep fracture. Particular interest is taken in determining the reaction products involved in creep cavitation and how these are connected to the powder surface reactions during the gas atomisation and consolidation (hot isostatic pressing).

3. Ti3SiC2 synthesis by powder metallurgical methods
Sammanfattning : The MAX phases constitute a group of ternary ceramics which has received intense attention over the last decade due to their unique combination of properties. The Ti3SiC2 is the most well studied MAX phase to date and it has turned out to be a promising candidate for high temperature applications. LÄS MER
4. Optimizing liquid phase sintering of ferrous powder metallurgical materials
Sammanfattning : The properties of powder metallurgical, PM, components are dependent on that the dilemma of full density and suitable microstructure is resolved. Whilst it is often possible to achieve full density, it may or may not coincide with a suitable microstructure. LÄS MER
5. Synthesis of Transition Metal Aluminides from Elemental Powder Mixtures
Sammanfattning : Structural components such as those used in gas turbines for energy conversion applications, are subjected to high loads at elevated temperatures. In order to ensure that the components survive under these conditions for a sufficiently long time, it is imperative to select materials with good high temperature properties like strength and corrosion resistance.
