The technical conditions of aluminum bronze optimized the hardening heat treatment technology of Cu14AlX aluminum bronze alloy through orthogonal experiment and comparison experiment, and found the primary and secondary order of the four elements that affect the hardening function of the alloy during the heat treatment process: solution temperature, aging time , Aging temperature and solid solution time. Further research proved that after 840～880℃ oil quenching solution and 570～600℃ air cooling aging treatment, the alloy can get the highest hardness of 48.2HRC

The reason for hardening is the uniform refinement of the ;2 phase separation and the dispersion and separation of the \; phase during the aging process.　 The hardness function of aluminum bronze alloy materials is related to many factors, such as pouring temperature, cooling rate, purification degree, heat treatment technology, etc. The correct selection and matching of heat treatment technical parameters during this period is one of the first ways to improve the hardness of alloy materials. The strengthening of aluminum bronze is mainly carried out through solid solution, deposition, dispersion and other methods.

The solid flexible copper tape of heat treatment, the temperature and time of aging and other factors are the primary factors that affect the phase transition and phase dispersion of the alloy. If everything is confirmed one by one through experiments The best matching value of technical parameters not only wastes a lot of manpower and material resources, but also fails to find a conclusive and reliable experimental conclusion. Therefore, the orthogonal experiment is selected, there are schemes, and the number of experiments is reasonably organized on the orthogonal table, and the experiment cycle is shorter, and the primary elements that affect the results are quickly found, so as to find better technical conditions.
