Abstract

The invention relates to a titanium alloy beta-phase high-temperature solid solution structure simulation method based on the remainder's theory. Comprising the following steps: establishing a titanium alloy beta-phase high-temperature solid solution atomic cluster possible proportion share formula by using titanium alloy components and electronic structure parameters calculated according to the Rolfe's theory; obtaining a characterization method of the number of nucleation points of each atomic cluster at different solid solution temperatures; proposing a beta-phase high-temperature grain growth rule based on atomic cluster binding energy or common electron logarithm on the strongest covalent bond and a life game rule; and performing titanium alloy beta-phase high-temperature solid solution structure simulation on a computer. The method is low in calculation cost, high in simulation precision and clear in physical significance in the simulation process.

Description

technical field [0001] The invention belongs to the field of titanium alloy structure simulation, in particular to a method for simulating high-temperature solid-solution structure of titanium alloy beta phase based on Yu's theory. Background technique [0002] Titanium and titanium alloys have properties such as high specific strength, corrosion resistance, good biocompatibility, and excellent high temperature stability, and are widely used in aerospace, chemical industry, ships, biomedical and other fields. much attention. At present, physical metallurgical models, neural networks, cellular automata, and phase field simulations are widely used in the simulation of iron and steel alloy structures. It is still difficult to be widely used in titanium alloys, so the research on microstructure simulation methods in titanium alloys is still not in-depth. In addition, there is no relevant report on the microstructure simulation of titanium alloy based on Yu's theory. Contents...
