摘要:

研究了Al_(87)Ni_(88)Y_5、Al_(86)Ni_(88)La_6、Al_(86)Ni_(88)Ce_6和Al浓度大于90 at.%的Al-Ni、Al-Y二元合金熔体的粘度随温度和时间的变化关系本文研究了Al-Y,Al-Ni-REM合金在固液相变后,由于基-非均质合金的非平衡态被破坏,发生了非单调弛豫过程。提出了非平衡熔体的非单调弛豫机制。

英文摘要:

The temperature and time dependencies of viscosity of the liquid alloys, Al87Ni8Y5, Al86Ni8La6, Al86Ni8Ce6, and the binary Al-Ni and Al-Y melts with Al concentration over 90 at.% have been studied. Non-monotonic relaxation processes caused by destruction of nonequilibrium state inherited from the basic-heterogeneous alloy have been found to take place in Al-Y, Al-Ni-REM melts after the phase solid-liquid transition. The mechanism of nonmonotonic relaxation in non-equilibrium melts has been suggested.
