摘要
本文分析了Y_2Fe_(17)N_y合金相的稳定性,用x射线和高温穆斯堡尔谱进行了实验研究。结果表明:虽然Y_2Fe_(17)N_y合金结构比较稳定,但仍为一亚稳相,因为当温度较高时,Y_2Fe_(17)N_y合金将分解成更为稳定的YN化合物和α-Fe相。
The structure stability of Y_2Fe_(17) N_y al-loys has been analyzed in details, and it has beenproved by X-ray diffraction and high temperatureM.ssbauer spectroscopy experiments also. It hasbeen indicated that although the Y_2Fe_(17)N_y alloysstructure was stable at room temperature ,it was also a metastable phase and could be decomposedinto stable YN compound and α-Fe at 750K.
