Effect of furnace atmosphere on sintering process of chromium-containing steel via powder metallurgy
Publikováno v:
Journal of Iron and Steel Research International. 28:889-900
During a powder metallurgy process such as sintering, the primary role played by the atmosphere in furnace is to prevent an excessive oxidation of powder compacts in case of the formation of oxides as residuals on powder surfaces. In particular, the

Powder metallurgy (PM) processing of steels typically results in a material characterized by residual porosity reducing the mechanical strength of the material. That is why mechanical components produced from PM steels for high demanding applications
