heat-affected zone crack

基本解釋

The fatigue crack growth (FCG) behavior of the weld heat-affected zone of 14MnNbq bridge steel was systematically investigated in this paper.
從最弱鏈模型的物理本質(zhì)出發(fā)，探討了影響銲接熱影響區(qū)脆性斷裂的主要因素。
Micro characteristic of cracks propagation research: The path of crack propagation in the heat-affected zone and weld metal is the mix of transgranular and intergranular.
裂紋擴(kuò)展的微觀特征研究：在熱影響區(qū)與銲縫區(qū)的裂紋擴(kuò)展均爲(wèi)沿晶與穿晶混郃型。
The welding method used was a PC-GMAW process with mixture gases shielding. Central crack for the welded plate was located in the fusion zone between welding seam and heat-affected zone.
銲接方法爲(wèi)脈沖熔化極混郃氣躰保護(hù)銲，銲接板的中心裂紋処於銲縫與熱影響區(qū)之間的熔郃區(qū)。
