    摘要:

    研究了低氧（氧含量為0.03vol%）TZM合金，在不同溫度下對其進行固溶熱處理，然后淬火。結(jié)果表明，合金的抗拉伸強度隨著固溶溫度的升高而逐漸降低，伸長率先增加后降低。隨著固溶溫度的升高，低氧TZM合金中析出的納米級富鈦相的含量逐漸增加。在1200和1300 ℃下凝固的樣品中出現(xiàn)了特殊的條形富鈦區(qū)域。納米級富鈦相確保了位錯在整個TZM合金中的均勻分布，同時顯著提高了低氧TZM合金樣品的塑性。

    Abstract:

    Low-oxygen TZM alloy (oxygen content of 0.03vol%) was subjected to solid-solution heat treatment at various temperatures followed by quenching. Results show that the tensile strength of the alloy gradually decreases with the increase in solid-solution temperature, and the elongation first increases and then decreases. The the amount of nanoscale Ti-rich phases precipitated in low-oxygen TZM alloys gradually increases with the increase in solid-solution temperature. Special strip-shaped Ti-rich areas appear in the samples solidified at 1200 and 1300 °C. The nanoscale Ti-rich phases ensure the uniform distribution of dislocations throughout TZM alloy, while significantly improving the plasticity of low-oxygen TZM alloy samples.
