This work presents the possibility of obtaining high density austenitic stainless steel parts by powder metallurgy (PM) and sintered in vacuum. Mechanical properties such as tensile strength, yield stress, elongation rate and Vickers hardness were measured by using a tensile testing machine and a Vickers hardness tester at room temperature. Microstructural characterization was performed by means of optical microscopy and scanning electron microscopy (SEM). The effect of sintering temperature on densification and mechanical properties of PM austenitic stainless steel has been investigated. The results show that density and mechanical properties were increased with the increase of sintering temperature, but when the sintering temperature is above 1340 °C, they increased slowly. The highest mechanical properties were obtained when sintering temperature was 1340 °C.

The microstructure of oxide scale formed in the early stage of oxidation of cold-rolled sheets of 17%Cr-Mn-Ni austenitic stainless steel was examined using SEM and TEM. Samples were oxidized at 973 to1373K for 1 to 15min. Nodules were observed on the surfaces of specimens oxidized at 1173K. The nodules were composed of two layers, which comprised Fe oxides and Cr-rich Fe-Cr-Mn oxides, respectively. The other scale was composed of two layers of Fe-Cr-Mn oxides with different compositions. Nodules were not observed on the surfaces of the specimens oxidized at 973 and 1373K. After oxidation at 1373K for 1min, the scale was composed of three layers. The first layer consisted of Fe-Mn oxides with a spinel structure, the second consisted mainly of Cr oxides, and the third consisted of Cr-Mn oxides containing a small amount of Fe.
