We analyze the thermal stability and kinetic parameters of crystallization of Fe 82 Nb 2 B 14 REM 2 (REM = Y, Gd, Tb, or Dy) amorphous metallic alloys by the method of differential scanning calorimetry. It is shown that the alloys based on iron crystallize in two stages. We compute the activation energy of both stages of crystallization of amorphous alloys according to the Kissinger, Ozawa, and Augis–Bennett models. The procedure of doping of the Fe 84 Nb 2 B 14 alloy with rare-earth metals leads to an increase in temperature, in the activation energy of crystallization, and in the frequency factor. The decrease in the crystallization rate constant of alloys caused by doping with rare-earth metals reveals their resistance to temperature treatment.

Fe82Nb2B14REM2非晶合金的热稳定性

我们通过差示扫描量热法分析了 Fe 82 Nb 2 B 14 REM 2 (REM = Y、Gd、Tb 或 Dy) 非晶金属合金的热稳定性和结晶动力学参数。结果表明，基于铁的合金分两个阶段结晶。我们根据 Kissinger、Ozawa 和 Augis-Bennett 模型计算非晶合金结晶两个阶段的活化能。用稀土金属掺杂Fe 84 Nb 2 B 14 合金的过程导致温度、结晶活化能和频率因子的增加。掺杂稀土金属导致合金结晶速率常数的降低揭示了它们对温度处理的抵抗力。
