weld -metal zone

基本解釋

The microstructure of the weld metal and the coarse-grained heat-affected zone are both granular bainite that consists of the bainite lath and the M-A constituent.
焊縫區(qū)和熱影響區(qū)粗晶區(qū)組織均為貝氏體板條和M-A組元組成的粒狀貝氏體；
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.
裂紋擴展的微觀特征研究：在熱影響區(qū)與焊縫區(qū)的裂紋擴展均為沿晶與穿晶混合型。
The basic requirement of welding the steel 2205 is that the weld metal and heat-affected zone obtain a favorable phase balance and retain the performance as the base metal after welding.
平衡鐵素體和奧氏體兩相組織在焊縫金屬和熱影響區(qū)中的比例，保證焊接接頭的性能，是雙相不銹鋼焊接的基本要求。
