TAWY合金中的B_2相，通过吸收和发射位错来协调变形，对高温塑性变形有益。
B_2 phase in TAWY alloy contributes to hot processing and coordinate the deformation with absorbing and emitting the dislocations.
另外大量之高温塑性变形可以产生较小之肥粒铁晶粒这样可以抵消高温热浸温度所造成之晶粒粗大效应。
Large amounts of deformation can lead to smaller ferrite grains which can balance the high temperature soaking effect.
耐腐蚀、耐高温，工作温度范围宽、蠕变小，长期工作无塑性变形。
C. The invention can resist corrosion and high temperature with wider working temperature and less creep deformation without plastic deformation after working long time.
