. Prolonging isothermal holding at 415 ℃ results in coarser and more spaced η phase particles at grain boundaries with wider precipitates free zone, and lower density of larger η′ hardening precipitates... precipitation of η phase first, and then S phase. Precipitates free zones are created around these coarse η and S phase particles after aging. Prolonging isothermal holding at these two temperatures......
分子动力学模拟Pb_(20)Au_(80)和Pb_(50)Au_(50)合金热力学性质的研究 刘大春1,贾国斌1,刘媛媛1,杨斌1 (1.昆明理工大学真空冶金国家工程实验室,昆明,650093) 摘要:采用分子动力学方法模拟了Pb_(20)Au_(80)和Pb_(50)Au_(50)合金体系的热力学性质,计算了不同温度下合金体系的生成焓,生成自由能,过剩自由能和结合能,从宏观和微观热力学角度分析了二元合金原子间的相互作用,得到的计算结果与实验数据很吻合. 关键词:分子动力学; 生成焓; 过剩自由能; 结合能; molecular dynamics(MD); enthalpy of formation; excess free energy; cohesive energy; [全文内容正在添加中] ......

-pure Ti3AlC2(U 240 mm). In addition, the first principle with quasi-harmonic approximation was applied for the thermodynamic properties’ investigation of Ti2AlC and Ti3AlC2, including Gibbs free energy, enthalpy, and entropy.With temperature increasing, Gibbs free energy increases,but enthalpy and entropy decrease. The present work provides the theoretical proof for the synthesis mechanism......
