  2. Standard practice for determining the metallographical constituent and inclusion content of steels and other metals by automatic image analysis - part 1 : determining the inclusion or second - phase constituent content of steels and other metals by automatic image analysis and stereology

    應用自動圖像分析測定鋼和其他金屬中金相組織夾雜物含量和級別的標準試驗方法第1部分:鋼和其他金屬中夾雜物或第二相組織含量的圖像分析與體視學測定
  3. 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、掃描電鏡等手段對低扭矩脆斷的bj212汽車輪殼螺栓的金相組織特徵，宏觀和微觀斷口形貌等進行了研究，結果表明：這種頭部薄的螺栓，滲層和淬透層過深，使頭部薄區脆斷抗力降低，在頭部與桿的根部，由於淬火應力不均勻導致根部產生拉應力，均是導致螺栓低扭矩斷裂的原因。
