1·The heat affected zone consists of grown grains.

热影响区的组织发生了粗化。

2·The concept of weld bead heat affected zone(WBHAZ) was proposed.

提出了“焊道热影响区”的概念。

3·The results show that the maximum residual stress appears in heat affected zone (HAZ).

结果表明，最大焊接残余应力出现在热影响区。

4·The influence of weld heating on microstructure of heat affected zone was investigated in this paper.

探讨了焊接加热对热影响区组织的影响。

5·The properties in weld deposit metal and Heat Affected Zone are strictly homogeneous with the base metal.

在焊接性能和热影响区金属矿床严格均匀与金属基材。

6·The microstructure in weld metal, heat affected zone (HAZ) doesn't change, but the grains in HAZ grow up.

焊缝金属、热影响区中的微观组织基本没有变化，但热影响区组织晶粒略有长大趋势。

7·This not only increase productivity, and cut parts can reduce the deformation and cut the heat affected zone seam.

这不仅提高生产率，而且能减少被割零件的变形量和割缝区的热影响区域。

8·There are some streamline microstructures and a slight grain melting in the heat affected zone on the side of pure copper.

接头紫铜一侧热影响区出现明显的须状组织，并有晶粒微溶的迹象。

9·The result of microstructures analysis show: there are melted zone , transient zone and heat affected zone in the laser melted layer.

对重熔区显微组织进行了研究，研究表明：激光重熔区分为熔凝区、过渡区及热影响区；

10·Most of the heat affected zone retained original structure characteristics of the base metal, and only a fraction of the zone remelted.

热影响区大部分保留了母材的原始组织特征，小部分区域发生了重熔。
