Small amount(0.5-0.8at.%) of niobium addition to the multicomponent alloys based on Fe3Al(Fe-28Al-5Cr-0.5Mo-0.05Zr-0.05B-0.1Ce) results in the microstructural refinement and the increase in the yield strength at temperatures up to 600℃,but is not beneficial to room temperature ductility.Results of m...

研究了Ｆｅ_３Ａｌ在９００－１３００℃、形变速率为１－１０~（－３）ｓ~（－１）的热压缩过程中的动态复原机制．结果表明，当Ｚ参数大于临界值时，该合金发生动态再结晶，反之则仅发生动态回复．动态再结晶是通过亚晶形核方式进行的．热压缩时真应力随真应变的增大而不断增加．所有的真应力—真应变曲线呈锯齿形（ｊｅ...
