Abstract

The modern concepts of the structure of liquid metals and alloys are considered. Several types of microinhomogeneity and microheterogeneity are shown to exist in liquid metal solutions. Their structural state changes as a result of variations in composition, history, temperature, and pressure or the influence of various external actions. Upon subsequent cooling at an appropriate rate, these changes can persist up to liquidus and affect the structure and properties of the solidified alloy. The main attention is paid to the influence of the heating temperature of a liquid metal. For aluminum-based alloys, the possibility of developing the optimum heat-treatment conditions for melting using the results of studying the structure and properties of melts has been shown. This optimized heat treatment of melts is shown to be an effective method to improve the quality of alloys.

熔体热处理对相应结晶锭或铸件结构和性能的影响

摘要

考虑了液态金属和合金结构的现代概念。液态金属溶液中存在几种类型的微不均匀性和微不均匀性。由于组成，历史，温度和压力的变化或各种外部作用的影响，它们的结构状态会发生变化。在随后以适当的速率冷却后，这些变化会一直持续到液相线，并影响凝固合金的结构和性能。主要关注液态金属的加热温度的影响。对于铝基合金，已经显示出通过研究熔体的结构和性能的结果来开发用于熔炼的最佳热处理条件的可能性。
