An investigation of the thermal stability of titanium alloy TA8 (Ti-5Al-2.5Sn-3Cu-1.5Zr) showed that the embrittlement was closely related to the surface structures of the alloy. The formation process of such surface structures has been discussed. On account of the fact that oxygen diffuses into the matrix of the alloy during thermal exposure, the precipitation of Ti_2Cu and α-ordered phase in high oxygen solid-soluted surface and/or near surface layers may play an important role in causing the embrittlement...

An investigation of the thermal stability of titanium alloy TA8 (Ti-5Al-2.5Sn-3Cu-1.5Zr) showed that the embrittlement was closely related to the surface structures of the alloy.

本文报导了TA8(Ti-5Al-2.5Sn-3 Cu-1.5 Zr)合金热稳定性的研究结果,提出了表面结构的脆化机理,探讨了表面结构的形成。认为,在热暴露时,由于氧向基体的扩散作用,在含有高浓度固溶氧的表面或近表层中,Ti_2Cu和a有序相的析出,在合金脆化中起主要作用。

By using the EPMA technique and the X-ray phase analysis we have studiedcompounds crystallized in the casting of wrought aluminium titanium-zirconium alloys. The results obtained were as follows: if the aluminum alloy contains Ti and Zr,tricompounds (Ti, Zr) Al_3 and (Zr, Ti) Al_3 instead of bicompounds ZrAl_3 and TiAl_3were formed.

本文采用电子探针和X光相分析的方法,对不同成份的Al-Ti-Zr合金及工业用7~#合金中的化合物进行研究。结果证明:钛和锆同存在铝合金中时,可形成Al-Ti-Zr三元化合物,其形状为块、棒、枝叉(随Ti、Zr比而异)。这种化合物为Zr溶于TiAl_3或Ti溶于ZrAl_3中的固溶体。上述结果,和金相的传统检验观念(认为棒状的是TiAl_3,枝叉状的是ZrAl_3)不同。

The evaporating rates of alloy elements from melts of Nb, Nb-W or Nb-W-Zr alloy at 3000-3600℃ have been examined by“melting ingot block”method. The activation energy of evaporation of Nb from Nb-W-Zr melt was obtained to be 175.9 kcal/mol. The rate-controlling step of the evaporation of Nb from Nb-W or Nb-W-Zr alloy is the detachment of Nb atoms from the liquid alloy surface, whereas the evaporation of Zr from Nb-W-Zr alloy seems to be a complex process. The evaporating rate of W from both Nb-W and Nb-W-Zr alloys,...

The evaporating rates of alloy elements from melts of Nb, Nb-W or Nb-W-Zr alloy at 3000-3600℃ have been examined by“melting ingot block”method. The activation energy of evaporation of Nb from Nb-W-Zr melt was obtained to be 175.9 kcal/mol. The rate-controlling step of the evaporation of Nb from Nb-W or Nb-W-Zr alloy is the detachment of Nb atoms from the liquid alloy surface, whereas the evaporation of Zr from Nb-W-Zr alloy seems to be a complex process. The evaporating rate of W from both Nb-W and Nb-W-Zr alloys, however, is controlled mainly by diffusion. The distribution of the alloy elements in the surface diffusion layer of quenched alloy melts has been determined by EPMA. It is measured that the thickness of diffusion boundary layer of Zr in liquid Nb-W-Zr alloy is 5.5—13.5×10~(-4)cm at 3080℃, and the concentration of Zr at surface is about 20% of that in bulk; the thickness of W diffusiin boundary layer is about 7—10×10~(-4) and 4—10×10~(-4)cm at 3120 and 3080℃ respectively, and the Wconcentration at surface is only 10% of that in bulk. A tentative estimation has also been made on the activity of coefficient of Nb or Zr. At 3000—3280℃ the activity of Nb in the Nb-W alloy is roughly equal to l. However, in the case of Nb-W-Zr alloy the Nb activity is much smaller, being 0.24 at 3600℃ and 0.17 at 3350℃. The apparent activity coefficient of Zr in Nb-W-Zr alloy is 0.16—0.31 at 3350℃ and 0.16—0.22 at 3600℃.

本文介绍了用“锭块熔化法”测定液态Nb,Nb-W与Nb-w-Zr合金在3000-3600℃时合金元素的挥发速率和用电子探针测定合金液表面扩散边界层内合金元素分布的结果,给出了各合金元素的活度系数值。实验结果表明,Nb自Nb-W-Zr合金中挥发过程的激活能为175.9kcal/mol,Nb自Nb-W与Nb-W-Zr中挥发的速率控制阶段为Nb原子自合金液表面脱离的蒸发过程;Zr自Nb-W-Zr中的挥发为混合速率控制阶段;W自Nb-W与Nb-W-Zr中挥发主要为扩散所控制。
