1. Liquid phase sintering of W-Ni-Fe composites : liquid penetration, agglomerate separation and tungsten particle growth
Sammanfattning : The initial stage of liquid phase sintering, involving liquid penetration, agglomerate separation, particle spreading and growth has been investigated in experiments using tungsten heavy alloys. The particle composites used were produced by hot isostatic pressing (HIP) of pure powder mixtures of W-Ni-Fe-(Co). LÄS MER
Sammanfattning : The present study intends to interpret the effects of alloying elements on microstructure and mechanical properties via liquid phase sintering of iron and steel powders. The tools involved are thermodynamic modelling, tailoring of powder properties and processing, and optimisation of sintering. LÄS MER

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
Sammanfattning : Cemented carbides based on tungsten carbide and cobalt arecommonly produced by a powder metallurgy route including liquidphase sintering. The pressed compact densifies to almost halfits volume during sintering due to pore elimination. LÄS MER
