摘要
Electric discharge sintering of high-speed steel R6M5F3 is studied. It is shown that powder hearing rate is mainly governed by the hear generated according to the Joule - Lenz rule and compaction mag. be described by equations that are valid for hot pressing. A new method is described for preparing billets for tools made from high-speed steel without some of the labor-intensive and expensive operations. This method combines electric discharge powder sintering with subsequent hot extrusion.
