Background Al-7% Si-Mg alloy has excellent _ manufacturability, zinc joint, corrosion resistance and heat crack resistance ', so it has been widely used in aerospace and transportation industry (such as aircraft structure, engine, Supu, aluminum rim____) . Among this series of alloys, A356 (0.25-0.45% Mg) and A357 (0.4-0.7% Mg) are the most common. Precipitation hardening can be achieved by various heat treatment methods to improve their mechanical properties. Precipitation hardening heat treatment method, the basic process includes the following steps: still temperature solution treatment-M & temperature floating-(quenching)-aging treatment (aging treatment) The purpose of high temperature solution treatment mainly has three points: (1 ) Dissolve Mg: Si particles, (2) homogenize zinc parts, (3) change the shape of eutectic silicon. The purpose of low temperature quenching: quenching this solid-solution phase to a temperature below the solution line to obtain a solid solution of Baohe. The purpose of aging treatment: aging treatment and then placing this supersaturated solid solution at constant temperature 'as it gradually precipitates to cause changes in properties, including strength, hardness, toughness, elongation, fatigue strength, stress corrosion resistance and electrical conductivity. The heat treatment methods proposed by previous researchers mostly focused on the conditional control of solution temperature and time or aging temperature and time, but there is no in-depth discussion on the variables of low temperature quenching, especially the maintenance time in the quenching fluid. So far, no one has discussed it. 2. Purpose At present, the T6 heat treatment condition of the Al-Si-Mg aluminum alloy used by the foundry industry is A7 (please read the Vi matters on the back and then fill in the Qiong page).

Description of invention (2) 525-545T solid solution 4-6 hours-20-60 ° C water quenching —Natural aging at room temperature for 24 hours-> 150-155 ° C artificial aging for 3-5 hours—180-190. (: Paint baking for 1 hour. In the entire heat treatment process, quenching is an important step mule, but it is ignored by the industry, which leads to an increase in product defect rate. Yong: After the solution treatment, the conditions for the product The effects of twisting and internal stress, and even subsequent age hardening treatment, are huge. The following further explains the shortcomings of the current methods used in the industry: (丨) The water quenching temperature is too low, which causes the distortion of the aluminum rim casting and the increase in internal stress. 2) The artificial aging treatment after low-temperature water quenching requires a long time to reach the cost of "strength 'causes waste of man-hours". (3) Low-temperature water; if the post-mortem is treated with temperature aging treatment 1 go ^ c) Although it can save processing time, it causes a sharp reduction in strength and stress corrosion resistance. (4) The entire heat treatment process' operation is complicated, the cost is too high, and the efficiency is too low. The purpose of the present invention is to provide a hot burial method that can quickly reach the age hardening strength, in particular, it is quenched with southern water (> 60. 0 'and maintained for a sufficient time (about 1 hour)) to facilitate the precipitation of strengthening phase Nucleation (nudeati〇nrate) and growth ^ ⑺ recognition ratio), and eliminate distortion and reduce internal stress. 3. The content and technical description of the invention The main reduction of the present invention is between the money and the money. Slow research shows that the precipitation rate of the strengthened phase is the nucleation rate and growth rate of the precipitate ^ rate = product, and both are affected by the supersaturation and diffusion rate, which is seven; The faster the rate, the faster its precipitation rate *, and the smaller it will be if it is full.

Description of the invention (3) The trend of change due to supersaturation and diffusion rate is opposite Therefore, the temperature must be selected to obtain the maximum precipitation rate, as shown in Figure 1. Water is the most widely used and extremely effective quenching fluid. The purpose of quenching is to prevent the i-equilibrium phase from being generated during cooling, so that the solution can obtain the maximum cooling and overplaning at low temperature, and suppress the formation of clusters of supersaturated solutes in vacancy, which is beneficial to the subsequent Aging precipitation hardening, but the quenching rate can not be too fast, so that castings produce severe distortion and residual stress. The present invention improves the heat treatment method of this series of alloys, which can solve the difficulties encountered in the industry at present. The improvement results are as follows: G) Elimination of product quenching distortion and internal stress: Because of high temperature (525uCo45 ° C) solution treatment After water quenching, the outer cooling is faster than the inside. The outside hardens and shrinks due to cooling, and the inside is compressed and plastically deformed, but when the inner Shao continues to cool and harden and shrink, it cannot be plastically deformed into the hardened outer layer. Therefore, the external part is compressive stress, and the internal part is tensile stress state. After Al_7% Si-〇.3% Mg alloy tensile test bar is treated at 540 ° C, the residual stress ratio at room temperature and water quenching is 25T: 10 (rC = 100Mpa: 25MPa) 'It can be seen 100. 〇The residual stress caused by water quenching is small. (2) Without reducing (or even improving) the mechanical properties of aluminum alloys, it can significantly reduce the time for manual aging and reduce costs. As shown in Figure 2, the Al-7Si-0.64Mg alloy is at 100. (: The water quenching temperature, and maintain a 60-minute immersion time, in the subsequent 16CTC artificial aging treatment conditions, the time required is far less than 25.
