Reduced temperature and pressure powder metallurgy process
Pressure powder metallurgy process for consolidating refractory or rhenium alloys using a reduced temperature and elevated pressure. Rhenium metal has high temperature strength and wear resistance but has a very high melting point as a pure metal and thus is difficult to use as a coating for many alloys having lower melting points.
