【Abstract】 A layer of hard sheet on the surface of steel parts can be built up by a combined heat-treatment process in which materials are reheated and quenched after nitrocarburizing treatment.In this paper,the alternation of mechanical properties and microstructures of the hardened surface was studied after the treatment of medium-car- bon nitroalloy 38CrMoAl.更多还原
