非晶态合金往往具有高强度和高屈服韧性等优异的力学性质,而且像结构弛豫和结晶化过程会对它产生明显的影响。只是以往的研究对象主要为金属-非金属型合金。在此,我们报道由前、后过渡金属所组成的金属-金属型非晶态合金的结构弛豫和结晶化效应。基于分析力学性质问题的复杂性,还把显微硬度的变化与差分比热、电阻率、超导临界温度、X射线小角散射和中子小角散射等测量结果作对照,并结合结构弛豫和结晶化动力学进行讨论。一、实验非晶态样品的制备方法和条件,以及对它作非晶态特性的检验,在文献[7]中已作报道。显微硬度测量在LEITZ DURIMET 2上进行。测量时,应保证凹坑深度在带总厚度的三分之二以内。由于非晶带各个方向的冷却速率有所差异,往往导致其硬度值因测量所选择的面不同
Amorphous alloys tend to have excellent mechanical properties such as high strength and high yield ductility, and they have a significant effect on structural relaxation and crystallization processes. Only the previous research object mainly metal - non-metallic alloy. Here, we report the structural relaxation and crystallization effects of a metal-metal-type amorphous alloy composed of front and rear transition metals. Based on the analysis of the complexity of mechanical problems, the changes in microhardness are also compared with the results of differential specific heat, resistivity, critical temperature of superconductivity, small-angle X-ray scattering and small-angle neutron scattering. Combined with the structural relaxation and Crystallization kinetics is discussed. First, the experimental amorphous sample preparation methods and conditions, as well as its amorphous properties of the test, has been reported in the literature [7]. Microhardness measurements were made on a LEITZ DURIMET 2. Measurement, should ensure that the pit depth of less than two-thirds of the total thickness of the belt. Due to the different cooling rates in all directions of the amorphous zone, it often leads to different hardness values due to the measurement of the selected surface
