| 10. | Abstract : by means of metallographical examination and sem , the microstructure characteristics , macro - and microfractographs of the brittle broken wheel hull bolt of bj212 automobile have been studied . the results show that the thin - headed screw , with excessively deep carbonitriding layer and hardening layer , has less resistance to brittle fracture in the thin area of its head . at the root of the head connecting the stem , a tensile stress may emerge owing to the non - even quenching stress . those are the two reasons for low torque fracture of bolt 文摘:借助金相、扫描电镜等手段对低扭矩脆断的bj212汽车轮壳螺栓的金相组织特征,宏观和微观断口形貌等进行了研究,结果表明:这种头部薄的螺栓,渗层和淬透层过深,使头部薄区脆断抗力降低,在头部与杆的根部,由于淬火应力不均匀导致根部产生拉应力,均是导致螺栓低扭矩断裂的原因。 |
