日本东芝公司开发出一种由烧结温度显著不同的钇与钨组合而成的高强度、高耐蚀性氧化物弥散强化钨合金。新开发的钨合金的主要特点是:四点弯曲强度为800MPa,大幅度超过纯钨的450MPa,而且可使熔融金属对其的腐蚀降低1/4～1/5。利用钇与钨的混合粉末的直接HIP(热静水压加工)固化,能够使强化粒子按亚微米级进行弥散。可以预料,新开发的上述钨合金不仅可以用作高强度、高耐热性材料,而且对于活性熔融金属而言,作为耐蚀性优良
Toshiba of Japan has developed a high-strength, highly corrosion-resistant oxide dispersion strengthened tungsten alloy, which is formed by a combination of yttrium and tungsten with significantly different sintering temperatures. The main features of the newly developed tungsten alloy are: four-point bending strength of 800MPa, substantially more than pure tungsten 450MPa, and the molten metal can reduce the corrosion of 1/4 ~ 1/5. Direct solid HIP (hydrostatic hydrostatic processing) curing using a mixed powder of yttrium and tungsten enables the strengthened particles to be dispersed in the submicron order. It is expected that the newly developed tungsten alloy as described above can be used not only as a high-strength, high-heat-resistant material but also as a corrosion-resistant material for an active molten metal
