摘要:
A consolidated complex shaped article having a density of at least 95 percent of theoretical density is prepared by placing a plurality of separate bodies in an arrangement, such that each separate body is in contact with at least one other separate body to form an aggregate body and wherein at least one of the separate bodies is essentially dense. The material of each separate body is comprised of a ceramic, a cermet or a metal. The aggregate body is then consolidated at a consolidating temperature superatmospheric pressure and time at temperature and time at superatmospheric pressure sufficient to form a consolidated shaped article. In consolidating the aggregate body, the consolidating temperature is a temperature that fails to form a liquid within at least one separate body and the superatmospheric pressure is applied for at least a portion of the time at the consolidating temperature.
摘要(中):
通过将多个分开的主体放置在一个布置中,使得每个独立的主体与至少一个其他分离的主体接触以形成聚集体,并制备具有至少95%的理论密度的固结的复合成形制品 其中所述分离的主体中的至少一个基本上是致密的。 每个单独的主体的材料由陶瓷,金属陶瓷或金属组成。 然后将骨料在固化温度超大气压力和时间在超过大气压力的温度和时间下固化,足以形成固结成型制品。 在固结聚集体时,固结温度是不能在至少一个单独体内形成液体的温度,并且在固结温度下至少部分时间施加超大气压力。
