Th Opportunities for conversion of powertrain parts from cast irons to PM

摘要

Recent developments in powder metallurgy(PM) technology have achieved mechanical propertieson a par with or exceeding those of current malleableand ductile cast irons. Francis Hanejko, ArthurRawlings and Robert Causton of Hoeganaes Corp comparethe properties of cast irons with those of selectedPM materials, and discuss the suitability of the PMprocess to replace cast and machined components inautomotive power-train applications.
