The effect of size and distribution of titanium carbide on the microstructure and mechanical properties of non-burning β titanium alloy Ti-25V-15Cr-2Al-0.2C-0.2Si (mass fraction, %) was investigated. The microstructure of the heat-treated and exposed alloy was studied using optical microscopy(OM), scanning electron microscopy(SEM) and transmission electron microscopy(TEM). It is found that carbides with finer size and more uniform distribution can suppress the formation of α precipitates more effectively, and can especially decrease the amount of grain boundary α precipitates after long-term exposure at 540℃ (the expected application temperature). Thus, significant improvement in thermal stability can be achieved by refining carbide particles in the matrix of the alloy.

碳化物和相是Ti-25V-15Cr-2Al-0.2C-x(x=0, 2%Mo, 2%Nb等)阻燃钛合金基体上的2种主要析出相。采用OM,SEM,TEM等方法研究了具有不同碳化物分布状态的Ti-25V-15Cr-2Al-0.2C-x合金的热处理及热暴露后的微观组织。结果表明,细小、弥散分布的碳化物颗粒不仅能细化合金的晶粒,而且能明显抑制对合金组织稳定性有害的沉淀相的析出。碳化物颗粒越细小、弥散,抑制相析出的作用就越强,合金的组织稳定性也越高。

采用TEM技术研究了具有不同热处理组织的Ti-25V-15Cr-2Al-2Mo-0.2C合金在540℃,250 MPa,100 h蠕变作用后的变形结构。结果表明:位错环组是合金蠕变变形结构中的典型位错组态;合金的蠕变抗力随β基体上弥散分布的第二相析出数量的增加而提高。添加微量能提高蠕变抗力的合金元素,如Si元素等,是改善合金蠕变性能的可行途径。

对Ti 25V 15Cr 2Al 0.2C阻燃β钛合金的微观组织、拉伸性能和变形机制进行了研究。结果表明:(Ti,V)C和α相是β基体上的2种主要析出相;高温长期热暴露(540℃,100h)后的合金晶界上形成连续的α膜,其塑性因此急剧下降;β基体在热暴露过程中发生微弱的短程有序化(SRO)转变,这在一定程度上破坏了合金的热稳定塑性;该合金室温变形以普通位错滑移为主要形变机制,热暴露后的变形结构中出现少量平面滑移带,位错的交滑移和攀移是合金540℃高温变形的重要形变机制。

The effect of heat treatment and thermal exposure on the microstructure and mechanical properties of non burning β titanium alloy Ti 25V 15Cr 2Al 0.2C (mass fraction, %) was investigated. It is found that the amount of α precipitation in samples after solution treatment followed by air cooling increases with increasing solution temperature. After solution treatment, the alloy was subjected to two different heat treatments to stabilize the material. The results show that the single ageing treatment(700 ℃, 4 h, AC) leads to a large amount of α precipitation, while the triplex treatment(850 ℃, 2 h, FC+700 ℃, 6 h, FC+540 ℃, 6 h, AC) significantly suppresses the formation of α precipitates. It is more important that after long term exposure at 540 ℃(the expected application temperature) samples heat treated by the triplex treatment have markedly higher ductility than those given the single aging treatment. The intermetallic compound TiCr 2 is observed in samples after long term exposure, which further degrades the ductility of the alloy.
