最近,美国得克萨斯仪器公司(TI)研制了一种纤维强化TiAl化合物箔材的新工艺,该工艺使材料的成本降低到与普通航空航天用镍基和钴基超合金相同,并且已经解决了工艺上的困难问题,使得冷轧工艺轧制出白TiAl箔材应用于其他领域中。 新工艺为:用等离子雾化形成TiAl预制板材,然后用TI的技术冷轧成箔板材。用等离子雾化方法直接生产箔材可以大大地提高生产量,在某种情况下可以增产80％多,比常规的熔铸方法增长 Recently, Texas Instruments Incorporated (TI) developed a new process for fiber-reinforced TiAl compound foils that reduced the cost of materials to that of conventional aerospace nickel- and cobalt-based superalloys and has addressed the process On the difficult issues that make the cold-rolled TiAl foil rolled out of white metal used in other fields. The new process is: the formation of TiAl plasma spray plasma prefabricated panels, and then use TI’s technology to cold-rolled foil sheet. Direct production of foil by plasma atomization can greatly increase throughput, in some cases yielding more than 80% more than conventional casting methods
