IRON-BASED POWDERS FOR POWDER METALLURGY

摘要

An iron-based mixed powder for use in powder metallurgy has an apparent density of at least about 3.1 Mg/m3, is excellent in die filling property an d compressibility and without segregation, and includes an iron-based powder t o which alloying powder is adhered at the surface by binder and free lubricant. The iron-based powder includes an atomized iron powder, or a mixed powder of an atomized ir on powder and a reduced iron powder.
