在国内和国外文献中,对钛铌合金的报导都很缺乏,然而这些合金在实际中却引起了一定的注意,因为铌和铝一样,能够大量地溶于α—钛中。因而当其将它与铝同时加入的时候,便能促进合金的强化。 由于均质范围很大,所以便有根据推测:这种合金将具有足够的塑性,因而也就能很好地承受压力加工。 关于钛铝钼合金方面,文献中已有一些叙述,并指出钼对于钛及钛铝合金的耐热性有良好的影响。例如含Al6％的钛合金在500℃下的持久(100小时)强度为22公斤/公厘~2,而含Al8％及Mo4％的钛合金在同样的
Titanium-niobium alloys are scarcely reported in domestic and foreign literature. However, these alloys have drawn some attention in practice because niobium, like aluminum, can be dissolved in a large amount in α-titanium. Therefore, when it is added with aluminum, it can promote the strengthening of the alloy. Due to the wide range of homogeneities, it is speculated that this alloy will have sufficient plasticity and therefore will withstand the stress well. In the titanium-aluminum-molybdenum alloy, the literature has been some description and pointed out that molybdenum titanium and titanium-aluminum alloy has a good impact on the heat resistance. For example, a titanium alloy containing Al 6% has a long-lasting (100 hours) strength of 22 kg / mm 2 at 500 ° C whereas a titanium alloy containing Al 8% and Mo 4%
