The composition of Fe-18mass%Cr-18mass%Ni alloy powder were prepared by mechanical alloying (MA) of three kinds of elemental powders. The MA powder became homogeneous by milled for 360ks. The hardness of powders MAed after 360ks were about 700Hv. The MA powder was consolidated by pulse current sintering (PCS) method at 1073K. The microstructure of this sample was fine and the hardness was about 400Hv. The sample consolidated by using powders milled in N<SUB>2</SUB> gas atmosphere contained much y phase. But the sample made by using powders milled in Ar gas atmosphere contained much a phase. Because the phase of powders as MA is almost a, the α -> γ transformation was occurred during heating of sintering. N<SUB>2</SUB> surpresses the γ ->α transformation during cooling.
