研究了微量V对DO3型Fe3Al基合金拉伸性能和组织结构的影响.结果表明,V可细化晶粒、改善Fe3Al合金室温强度和塑性,室温拉伸断口也由芽晶解理型转变为解理加沿晶混合型.V还使Fe3Al合金高温强度峰值对应的温度提高约200℃,从而提高Fe3Al合金使用温度.

The effect of alloying element V on tensile properties and microstructure of DO3Fe3Al-based ordered alloy at room and elevated temperatures have ben investigated. The results show thatV can fine grains, improve strength and plasticity of the alloy, and va
