Abstract

The invention discloses a formula and a smelting key technique for a high-strength and high-tenacity aluminum alloy. The high-strength and high-tenacity die-casting aluminum alloy has good casting performance, mechanical performance and thermal treatment performance, and also has high strength and tenacity, so that the mechanical performance of the aluminum alloy is good; recording of cicada chirping is placed in a metal fluid in the smelting key technique, so that characteristic sound vibration of cicada chirping can spread in the metal fluid; according to observation, sound vibration of cicada chirping can generate more scattering and dissipating in a spreading medium compared with sound vibration with more low-frequency components; and more ripples can be motivated on the surface of themetal fluid.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to the formulation of high-strength and high-toughness aluminum alloys and key technologies for smelting them. Background technique [0002] Aluminum alloy is a common lightweight metal material. It is widely used in industries such as automobiles, ships, aerospace, machinery, and communications. It has the characteristics of good processing performance, light weight, and energy saving. With the continuous development of the automobile industry, the requirements for light weight and low energy consumption of automobiles have become a major trend in the automobile manufacturing industry, and the demand for aluminum alloy, which is the first material for light weight, in automobiles is also expanding. Most of the aluminum alloy parts used in automobiles are formed by casting. Compared with other processing methods, casting has high metal utilization rate and high dimensional a...
