  1. 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:藉助金相、掃描電鏡手段對低扭矩脆斷的bj212汽車輪殼栓的金相組織特徵,宏觀和微觀斷口形貌進行了研究,結果表明:這種頭部薄的栓,滲層和淬透層過,使頭部薄區脆斷抗力降低,在頭部與的根部,由於淬火應力不均勻導致根部產生拉應力,均是導致栓低扭矩斷裂的原因。
