| Abstract: | By overall examining and experiment analyses of the pattern,fracture,inside quality and microstructure of the invalid casting,the conclusion were acquired that the inside quality question,cold cracks,large quantity of scattered pores and unmodified structure lead to the piston cracking and becoming invalid during the early service. |
