Calculations of some thermo-physical properties of aluminum alloys using data of thermal analysis

Abstract

Increasing the accuracy of computer simulation of the crystallization processes of aluminum alloys and the solidification of castings requires reliable data on the thermo-physical properties of the alloys used. The present paper describes a technique for calculating the heat of crystallization and heat capacity of aluminum alloys in the range from the temperature of its pouring into the mold to the average temperature of the solidified skin according to the results of thermal analysis. The proposed technique can be used to determine the values of thermo-physical properties of aluminum alloys in industrial and research laboratories and centers involved in production of high-quality castings.
