ATTAINMENT OF ALLOYING BETWEEN SOLID PHASE AND LIQUID PHASE OF POWDER MIXTURE AND PRODUCTION OF SINTERED METAL MOLDED BODY

摘要

A master alloy powder is formulated for admixture to an iron based powder to provide liquid phase sintering and production of a substantially homogeneous product having the characteristics of a wrought alloy product. The master alloy powder contains at least two elements selected from the group consisting of manganese, nickel molybdenum, chromium, copper, carbon and iron. The master powder may contain additions of silicon up to 5% and rare earth metals up to 2%, either of which assist to speed up diffusion and create a more favorable liquidus- solidus relationship within the master alloy powder.
