what is powder forging
âPowder Forging is a process in which unsintered, presintered, or sintered powder metal preforms are hot formed in confined dies. The process is sometimes called PM (powder metallurgy) forging, PM hot forming, or is simply referred to by the acronym P/F.DF (902.1 KB). Previous experimental work demonstrated that rolling contact fatigue durability of high-density powder metallurgy samples was influenced by depth of surface densification (achieved via roll densification), sintering temperature, and heat treat practice.
