“…The use of powder metallurgy (P/M) components in the automobile industry has improved engine performance, as well as reduced its cost 14,15 . The use of either HSS or high-alloyed steels for sintered parts is a consolidated option for this application due to its good mechanical properties, corrosion resistance, high thermal conductivity and good machinability [16][17][18][19][20][21] . The quenching or cooling of the workpiece from the austenitic zone transforms the austenite that forms at the high temperature to a harder martensitic microstructure 22,23 .…”
