基于Pandat的Ti-Al系相图计算及热力学评估
Thermodynamic Calculation and Assessment of Ti-Al System Based on Pandat
摘要
Abstract
Phase diagram of Ti-A1 system was researched through the calculation using Pandat 2016 thermodynamic calculation software,the latest database of Ti alloy and reasonable thermodynamics models based on Phase diagram calculation theory.The calculated phase diagram was then assessed by phase rule,by analysing the specific points of the phase diagram,the phase areas,the phase transition points and so on.The calculated results show that the calculated phase diagram matches experimental phase diagram very well,laying a foundation for extrapolated phase diagram of ternary system and more.Their relative errors are almost below 5％.As compared with the empirical formula for (α-+-β)/β phase transition points of Ti-A1 system,the new calculated formula proposed is more accurate,having some reference value and academic significance.Its confidence level is 99.982％.关键词
