此外，利用该技术焊接细晶粒钢时，可以完全避免热影响区软化的现象。

Furthermore , softening of HAZ can be avoided when the UNGW is used to weld fine grained steel .

细晶粒钢焊接接头热影响区晶粒粗化引起的屈服应力的局部下降，对接头安全性的影响需要做出定量评价。

Local decrease of yielding stress due to grain coarsening in the heat-affected zone ( HAZ ) of fine-grained steel welded joint affects the security of the joint so that a quantitative evaluation of this effect need to be made .

通过热处理实验，探讨了945钢组织遗传倾向，试验结果表明，945钢晶粒长大倾向较小，为本质细晶粒钢。

The tendency of structure inheritance of 945 steel was investigated with heat-treatment process in this paper . The result shows that the tendency grain growth of 945 steel is of refined and the 945 steel is of refined , grain in essence .

并相继研究开发了铌钒微合金化技术、电炉流程微合金钢铸坯质量控制、细晶粒钢生产和控轧控冷等新技术。

To develop these steels , a lot of technologies involved with steelmaking and rolling process have been adopted . They include niobium and vanadium micro-alloying technology , microalloy slab quality control in EAF process , production of the ultra-fine grained steels , controlled rolled and controlled cooled , etc.
