description: In this paper, we investigate the reason for the rejection of aluminum bronze BrAZHNMts9-4-4-1, which is a technology of reduced impact strength after heat treatment, and a technology for its elimination is also proposed. Tasks solved in the course of research:
1. The study of technological features of production and consideration of the causes of the defect.
2. Development and conduct of experiments to eliminate defects in the technology of hot deformation of semi-finished products.
3. The study of the alloy microstructure, ratio and phase morphology during various types of heat treatment, as well as their effect on mechanical properties.
During the experiment, heat treatment was carried out according to the developed regime. The study conducted tests for static tension and shock bending. The fractures and microstructure of the samples were studied. The result of the work was an increase in the toughness of the defective material and the establishment of the cause of reject.
The reason for the low mechanical properties of aluminum bronze is revealed - the heterogeneity of the structure of the material in the delivery state, and the toughness of the material is increased.
