Influence of oxygen partial pressure in sintering atmosphere on properties of Cr-Mo prealloyed powder metallurgy steel

Chromium is an attractive alloying element in low alloyed steels since it gives good hardenability at low cost. The drawback with using chromium in powder metallurgy (PM) grades is its high affinity for oxygen. Thermodynamic calculations show that the oxygen partial pressure should be
