PtW_(8.5)和PtW_(8.5)Re_5Ni_2两种合金(以下简称PtW和PtWRe_5Ni_2)经过再结晶或稳定化处理后出现热电性能的反常现象,即所谓的K状态。这一反常现象的出现表明与一般固溶体不同,当合金在高温下长期退火或缓慢冷却时电阻增加,冷加工时则又减少。合金经冷加工(以下称硬态)和再结晶处理后其室温和高温电阻的变化亦不同,说明与合金的组织状态有关,为此有进一步探讨的必要。
PtW_ (8.5) and PtW_ (8.5) Re_5Ni_2 two alloys (hereinafter referred to as PtW and PtWRe_5Ni_2) after recrystallization or stabilization of the thermoelectric properties appear after the anomaly, the so-called K state. The appearance of this anomaly shows that, unlike ordinary solid solutions, resistance increases as the alloy is annealed at long-term or slow-cooling at high temperatures, and decreases as cold work. Alloy by cold working (hereinafter referred to as the hard state) and recrystallization treatment of its room temperature and high temperature resistance changes are also different, indicating the organization of the alloy state, for further exploration of the need.
