中文摘要:
      通过Calphad方法优化了Ti-Al-Fe-Mn四元系数据库,利用此数据库计算了四个子三系相关相变温度,并与已有的实验数据进行了对比和讨论,结果符合很好,证明了由此四元数据库计算各相变温度的可靠性。再通过该数据库计算了Ti-Al-Fe-Mn四元系一系列合金的α+β/β相变温度,并将计算结果与前人的经验公式计算结果进行了对比,在此基础上建立了更准确的计算该体系相变温度的经验公式。上述结果可为钛合金相变温度的确定提供一种可行的方法。
Calculation of beta transus temperature of Titanium alloys by Calphad method
英文关键词:Calphad  Ti-Al-Fe-Mn  beta transus temperature
英文摘要:
      The Ti-Al-Fe-Mn thermodynamic database was optimized by Calphad method. Based on this database the beta transus temperatures of four ternary systems in Ti-Al-Fe-Mn system was calculated and they were good agreement with experimental values. In this way the reliability of Ti-Al-Fe-Mn quaternary systems was verified. Then α+β/β phase transformation temperatures of a series titanium alloys were calculated by Calphad method and compared with values that previous formulas calculated. Also, a more accurate formula was established based on the values calculated. This results may provide a feasible way for the determination of titanium beta transus temperature.
