铝合金是工业中应用最广泛的一类有色金属结构材料,在航空、航天、汽车、机械制造、船舶及化学工业中已大量应用.纯铝的密度小（ρ=2.7g/cm3）,熔点低（660℃）,铝是面心立方结构,故具有很高的塑性（δ:32~40%,ψ:70~90%）,易于加工,可制成各种型材、板材.抗腐蚀性能好；但是纯铝的强度很低,退火状态 σb 值约为8kgf/mm2,故不宜作结构材料.通过长期的生产实践和科学实验,人们逐渐以加入合金元素及运用热处理等方法来强化铝,这就得到了一系列的铝合金.
此次制备铝基合金材料,加入了8％的Cu作为融入金属,经过11小时固溶处理；测试硬度后再陆续进行2—9小时时效处理,最终得到此次试验样品.通过测试其硬度,得到试样时效处理时间与其硬度关系；再经过试样的磨平抛光及腐蚀处理,得到可观察其金相组织的试样,观察其金相组织结构,可得出其内部组织；从而得到其相关性能的结论.

Aluminium alloy is the most widely used in industry of a class of non-ferrous metal structure material, in aviation, aerospace, automotive, machinery manufacturing, shipping and the chemical industry has a large application. The density of pure aluminum small (ρ = 2.7 g/cm3), low melting point (660 ℃), aluminum is face heart cubic structure, it has high plastic (delta: 32 ~ 40%, ψ: 70 ~ 90%), easy processing, can be made into all profiles, the plank. Corrosion properties is good; But the strength of the pure aluminum is very low, annealing state sigma b value is about 8 KGF /, it should not be as was the structural materials. Through the long-term production practice and scientific experiments, people gradually to join alloy element and using the method such as heat treatment is to strengthen the aluminum, this will be a series of aluminum alloy.
The aluminum alloy material preparation, added 8% Cu as metal, after 11 hours into solid solution treatment; Test hardness in again after play 2-9 hours, finally obtained the aging treatment of the test samples. Through the test its hardness, get the sample aging treatment time and hardness relations; And then after the polishing and grinding smooth, get observable corrosion treatment the microstructure of samples, observe the analysis of metallographic organization structure, can be concluded that the internal organization; And get the related properties of the conclusion.【这个可能会专业点、】
