1. 1. On the processing of starch consolidated high speed steel - Microstructure and tribological properties

   Författare :Peter Harlin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribological properties; green body; microstructure; porosity; high speed steel; Starch consolidation; super solidus liquid phase sintering; mechanical properties;

   Sammanfattning : This thesis focuses on processing of high speed steel (HSS) powder into components using starch consolidation (SC) and supersolidus liquid phase sintering (SLPS). The work consists of four parts. First, the possibilities and constrains of the SC process are investigated and the role of starch in the green body fabrication clarified. LÄS MER
