Abstract
Pores are important characteristics in powder metallurgy alloy parts. The effect of processing parameters on pore size is discussed. If pore size can be controlled as small as several or tens of nanometers in PM alloy parts, the parts may gain special physical or mechanical properties. The challenge to obtain pores sizing in several or tens of nanometers in PM alloy parts is discussed.
