Title:
POWDER METALLURGICAL METHOD FOR PRODUCING HIGH-DENSITY SHAPED PARTS
Document Type and Number:
WIPO Patent Application WO2002055747
Kind Code:
A8
Abstract:
The invention relates to a powder metallurgical method for producing high-density shaped parts from an alloy consisting of, apart from at least 20 wt. % chromium, iron and of one or more additional alloy proportions whose sum does not exceed 10 wt. %. According to the invention, the production ensues by compacting the powder feedstock approximately into its final shape and by sintering the same, whereby the additional alloy proportions are introduced in the form of a master alloy powder. The master alloy is comprised of, as desired: the additional alloy proportions and of the iron proportions; or of the additional alloy proportions, of the iron proportions and of the chromium proportions; or of the additional alloy proportions and of the chromium proportions.
