以AuCu3-亚格子系统为例,介绍3项发现:第一,迄今阻碍金属材料科学进步的第三大障碍是研究者们习惯用平衡均匀转变的思维方式认识温度极其缓慢变化的合金相变实验现象,然后以实验现象的错误认识为选择信息,建立Gibbs能函数和所谓的“平衡相图”;第二,AuCu3-型亚格子系统的平衡全息网络相图可用来描述与成分和温度有关的合金基因排列结构和各种热力学性质的系统相关性;第三,每个合金的平衡转变都是均匀的单相转变,不是非均匀的双相转变,存在一条没有有序相和无序相共存区的单相相界线,相界线顶点成分和温度远偏离AuCu3化合物临界点的计量成分和温度。
Taking the AuCu3-subgrid system as an example, we present three findings: First, the third major obstacle to progress in the sciences of metallic materials has so far been that researchers are accustomed to recognizing the alloy phase transition experiments with extremely slow temperature changes in a balanced and balanced way of thinking Secondly, the balanced hologram network of AuCu3-type subgrid system can be used to describe the Gibbs energy function and the so-called “equilibrium phase diagram” The systematic correlation of the arrangement of the relevant alloy genes and various thermodynamic properties; thirdly, the equilibrium transformation of each alloy is a homogeneous single-phase transformation, not a non-uniform two-phase transformation, and there is an unordered phase and disorder Phase coexistence zone single-phase boundary line, phase boundary line vertex composition and temperature far from the critical point of the AuCu3 compound measured composition and temperature.
