【Abstract】 On the basis of fundamentals of chemical erosion,this paper expatiates a method of displaying the hardenedsteels austenitic crystallite boundary with a corroding agent confirmed by repeated experiments Experimental results indicate this corroding agent,When used to exhibit the austenitic crystallite boundary of steel 45 and 40Cr in hardend state, is effective to restrain inner phase organization and reveals the grain boundaries更多还原
