发展目标洛克希德公司已经确定了某些对铝材的改进十分重要的发展领域,并将其总结于图1,其中包括三类铝合金材料.第一类新的铝材是比重低于常规铝合金的铝-锂合金.由于这种材料重量轻,因而可与合成材料相比.事实证明,这种新型低比重铝合金已经在广泛地应用.第二类铝合金是正在发展中的高温铝合金.这种合金可与钛合金相媲美,由于其成本低、重量轻而更加令人瞩目.这种材料可用于高速航空器上,所承受的最高温度可达650°F(345℃).
Development Goals Lockheed has identified certain areas of development that are important for the improvement of aluminum and summarized it in Figure 1, which includes three types of aluminum alloys, the first of which is a new aluminum with a lower specific gravity than conventional Aluminum alloy of aluminum - lithium. Due to the light weight of this material, which can be compared with the synthetic material has proved that the new low specific gravity aluminum alloy has been widely used. The second type of aluminum alloy is the development of high temperature This alloy, comparable to titanium, is even more impressive due to its low cost and light weight, which can be used on high-speed aircraft and can withstand temperatures up to 650 ° F (345 ° C).
