今后二十年将是有色金属和合金飞速发展的时期,即将出现真空铸铜的连续加工工艺,可制得结构更佳、纯度更高和不含气体杂质的铜。强度高达10～15万磅/吋~2,具有高电导性和热导性的铜合金将采用添加金属纤维提高强度、急冷、弥散强化和沉淀硬化的联合工艺进行生产。它是制造融熔反应器和气体涡轮机的必需材料。牌号为C1700(Cu1.9 Be0.25 Co)的合金现在是而且在今后二
The next two decades will be a period of rapid development of non-ferrous metals and alloys. The continuous processing of vacuum cast copper is about to occur. Copper with better structure, higher purity and without gaseous impurities can be obtained. Strength of up to 10 to 150,000 pounds / inch ~ 2, with high conductivity and thermal conductivity of the copper alloy will be added to increase the strength of metal fibers, quenching, dispersion strengthening and precipitation hardening of the joint production. It is a necessary material for making fusion reactors and gas turbines. Alloy C1700 (Cu1.9 Be0.25 Co) is now and in the next two
