Abstract
Particle reinforced metal matrix composites (MMC) based on cold work tool steels are increasingly used as wear resistant materials. Superior wear properties compared to commonly used wear resistant materials justify their application. Usually such materials are produced by means of powder metallurgy (PM) and hot isostatic pressing (HIP), a comparatively cost-intensive process. Against this background a sintering route based on super solidus liquid phase sintering (SLPS) was developed to obtain MMC with properties comparable to those produced by means of HIP. This publication points out the processing route in detail and focuses on the resulting microstructures. Finally, some results of wear tests are presented in comparison to MMC produced by HIP (HIP-MMC).
