Thermal analysis of the crystallisation process allows accurate calculation of latent crystallization heat of various phases crystallising during solidification. Based on the assumption, that the latent crystallization heat is proportional to the share of various phases in the alloy microstructure, the thermo-derivative analysis allows also the calculation of the amount of crystallized phases. Calculation of the above-mentioned properties is based on the characteristic points determined in a differential curve. Properly selected chemical composition of the alloy, as well as the appropriate cooling rate and heat treatment conditions lead to improvement of functional properties of manufactured elements. Therefore it is very important to know how the changes of the cast structure in relation to the change of the cooling rate and chemical composition [1]. The purpose of this research work is to investigate the thermo-derivative interdependences occurred in the analysed copper alloys using Universal Metallurgical Simulator and Analyzer (UMSA) [2]. In this paper was also investigated the influence of the heat treatment conditions on the structure of nickel copper. |
