Question

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。

Answer 1

Aluminum is the industry's most widely used class of non-ferrous structural materials in aerospace, automotive, machinery, shipbuilding and chemical industries has been a large number of applications. Aluminum's density (ρ = 2.7g/cm3), low melting point (660 ℃), aluminum is face-centered cubic structure, it has a high plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), ease of processing, can be made into a variety of profiles, sheets. Good corrosion resistance; but the strength of aluminum is very low, annealed σb value of approximately 8kgf/mm2, it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually to include the use of alloying elements and heat treatment and other methods to strengthen the aluminum, which has been a series of aluminum alloy.
The preparation of aluminum alloys, 8% of Cu added into the metal as, after 11 hours solution heat treatment; test the hardness after aging treatment after another for 2-9 hours, finally get the test samples. By testing its hardness, to get the specimen hardness with aging time relationship; then polished and polished specimen after corrosion treatment, get to observe the microstructure of the samples, to observe the metallographic structure, can be drawn from its internal organizations; to be related to the performance of its conclusions.

Answer 2

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、】本回答被提问者采纳
