用急冷方法得到的非晶态合金,当处于淬火态时,具有高度的无序结构.它不仅相对于结晶相、而且相对于较其稳定的玻璃态,也是亚稳态.在研究金属玻璃热稳定性和晶化行为过程中,对淬火态的金属玻璃,在远低于玻璃转变温度(Tg)的条件下加热退火,材料将会发生明显的低温结构弛豫,使其趋向于自由能更低的较稳定的玻璃态,并伴随有居里温度、磁各向异性、电阻、比热和硬度等的改变.目前,关于金属玻璃的结构弛
The amorphous alloy obtained by the quench method has a highly disordered structure when quenched, and is metastable not only to the crystalline phase but also to its stable glassy state, In the process of stability and crystallization, the quenched metallic glass is heated and annealed far below the glass transition temperature (Tg), and the material will undergo significant low-temperature structural relaxation, which tends to be more free energy Low and stable glassy state with the change of Curie temperature, magnetic anisotropy, resistance, specific heat and hardness etc. At present, the structural relaxation of metallic glass
