Comparison of measured and calculated thermophysical properties of nickel super-alloys

摘要

Three real grades of nickel super-alloys (IN 713LC, IN 738LC and IN 792-5A) were investigated and values of temperaturesof phase transformations and latent heats of melting were obtained. All investigated quantities are very importantfor thermodynamic and kinetic modelling. Moreover, these data are also valuable for a lot of software used fortechnological processes modelling. Experimental values were obtained using Differential Thermal Analysis (DTA)measurements. Calculations were performed using Thermo-Calc 3.1 software with the use of three different databases(SSOL5, TTNI8 and TCNI6). Comparison and discussion of experimental and calculated data was performed.
