In this paper, the characteristic of physical metallurgy in (?)he solidification processes of TIG weld bead had been studied for Hf-bearing cast nickel base superalloys. The results have shown that Hf lowers the sensitivity to weld cracking appreciably, Hf increases the volum percent of eutectic γ+γ' in alloys, widens the solidification temperature range and promotes the interlink of interdendritic small pools in a wide temperature range. Hf-rich melts have good fluidity, wettability and skin effects at the later stage of solidification. The skin melts are a multicomponent eutectic liquid that contains Hf above 6% by wt. and have the capability of self-brazing and the recovery effect on cracks. These results proved that solidification range of alloys is not the only factor influencing weld cracking. The physical and chemical properties of ultimate solidification liquid have also an important effect.

对含铪铸造高温合金在TIG焊接凝固过程中物理冶金特性的研究结果表明,铪显著降低合金焊接裂纹的敏感性。铪增加合金r+r’共晶量并扩大凝固温度范围,使合金枝晶间微液池在很宽温度范围内相互连通。凝固后期富铪熔体具有良好的流动性和润湿性并具有趋肤效应,趋肤液是含铪量高于6%的多元共晶液,它具有自钎接性能,对裂纹起“自愈合”作用。这些结果证明,合金凝固范围宽窄不是影响焊接裂纹的唯一因素,最后凝固液体的物理化学性质具有重要作用。
