急冷速度是形成非晶态合金的动力学条件。低于临界冷却速度时,结晶体体积分数随冷却速度降低而增加,并逐步向平衡态过渡;高于临界冷却速度时,随冷却速度增加,体系的混乱度增大。在此情况下,相应非晶态的结构和性能会怎样变化?国外有些工作已初步涉及~([1,2]),研究结果基本上是定性的,许多问题尚无定论。本文实现了对非晶态合金形成过程中冷却速度的直接测定,在更可靠的物理和数学模型基础上研究了非晶 Chilling rate is the kinetic condition for the formation of amorphous alloys. When the critical cooling rate is lower than the critical cooling rate, the volume fraction of the crystal increases with the decrease of the cooling rate and gradually transitions to the equilibrium state. Above the critical cooling rate, the chaos of the system increases with the increase of the cooling rate. In this case, how does the corresponding amorphous structure and properties change? Some work in other countries has initially involved ~ ([1, 2]). The research results are basically qualitative and many problems are still inconclusive. In this paper, the direct measurement of the cooling rate during the formation of amorphous alloy has been realized. Based on the more reliable physical and mathematical models,
