A solid solution composed of two or more elements, after melting at high temperature, will recrystallize as the temperature decreases to form a solid solution. During the recrystallization process, the concentration of elements with low concentration and high concentration of element crystals in the solution is different. During the crystallization of solid solution, if the … Read More
