| Abstract: | Alloys Fe3-xCrxSi(x=0,0.2,0.4,0.6)were prepared with the method of mechanical activation combined with hot-pressed sintering.Their phase was analyzed by using X-ray diffraction,the corrosion resistance performance of alloys was investigated with soak corrosion and electrochemical corrosion,and their surficial morphology after corrosion was observed with scanning electron microscope.The result showed that after the addition of Cr,the crystal structure was not changed and the main phase was still Fe3Si.With t... |
