Abstract
Analysis is given on the cracking and fracture of machine parts made of 45 steel during the proces sing from the view points of metallurgical quality,the influence of the steel's chemical composition on its quenching temperature,the cross section size of the machine parts,the imperfection in design of the parts,and the surface injuring during machining cutting.Ways for avoiding the cracking and fracture are proposed.
