1. Novel approaches for achieving full density powder metallurgy steels
Sammanfattning : Powder metallurgy (PM) is one of the most resource-efficient methods for manufacturing structural components with complex shapes. The utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. LÄS MER
2. Net-Shape Consolidation of Water-Atomised and Gas-Atomised Steel Powder Towards Full Density
Sammanfattning : Powder metallurgy (PM) provides resource- and cost-efficient routes to create near-net shape products compared to conventional metal fabrication techniques. To improve the mechanical performance of PM steels, it is a prerequisite to enhance the density of the material. LÄS MER
3. Biomaterial Components Prepared by Titanium Powder Technology
Sammanfattning : The main objectives of this work were twofold: First, to determine if a pressed-powder method could be used to fabricate titanium dental copings, and to line out what problems or benefits this new method would have. Second, to test if high velocity compaction of titanium powder could be used to form biomaterial components such as copings or dental implants. LÄS MER
4. Modelling and simulation of powder pressing with consideration of friction
Sammanfattning : Finite element modelling and simulation of the powder pressing process can be used in the rational development of powder metallurgy (PM) components. Many of the nonlinear finite element (FE) codes available today can be used for powder pressing simulations. LÄS MER
5. The isostatic pressure processing of high Tc superconductors and their properties
Sammanfattning : The high Tc superconductors are highly anisotropic, ceramic materials which makes it difficult to sinter them at atmospheric pressure to full density. High porosity is detrimental to their mechanical and electrical properties, so the use of isostatic pressures was used to give higher density materials with improved properties. LÄS MER
