摘要： This invention relates to a method for producing alloy and intermetallic powders. Particularly to a method for the production of titanium based alloy and intermetallic powders. A first metal and a second metal oxide powder are mixed with a controlled metal/metal oxide molar ratio. This mixture is heated, becomes self propagating and leads to formation of a mixture of alloy liquid and a oxide solid. Pressure is applied to separate the phases and upon cooling produces a metallic solid. FIG. 1a shows an example of a solid crushed into a powder as produced by this method.

摘要： A frictional false twister is disclosed. The twister has a plurality of rotating friction plates located between the nip of the front rollers and the yarn guide. The friction plates are staggeringly arranged for rubbing a twisted yarn. The spinning direction of the twisted yarn is opposite to the rotating direction of the friction plates. Through the action of the frictional false twister, the twist of the yarn between the false twisting device to the front nip can be increased, shortening the twisting triangle height, and increasing the spinning strength. As the yarn and the outer surface of the friction plate make relative sliding and rubbing, the friction damping force correspondingly reduces the spinning tension in the twisting triangle.

摘要： Titanium based metal matrix composites reinforced with ceramic particulate are well known, based on a blend of titanium alloy powders with ceramic powders, e.g., aluminum oxide powders, utilizing a low energy ball milling process, followed by cold compacting and sintering to produce an appropriate composite. This prior art process is disadvantaged from the point of view that there are virtually no particles in the blend below the micrometer size range, which lack has a deleterious effect on the subsequent processing of the composite. This problem has been overcome by utilizing dry high energy intensive milling in the process, which has the effect of providing the necessary number of small particles below the micrometer size range as well as enhancing the reactivity of different particles with one another. In order to produce a titanium base alloy alumina metal matrix composite, titanium dioxide powder is blended with aluminum powder and subjected to dry high energy intensive milling until the separate particle phases achieve a size of 500 nanometers maximum. The intermediate powder product is then heated to form the titanium alloy/amumina metal matrix composite in which the ceramic particles have an average diameter of no more than 3 &mgr;, and the oxide consists of more than 10% and less than 60% by volume fraction of the total composite. The composites have extensive application to tough and strong engineering alloys.
摘要翻译： 用陶瓷颗粒增强的钛基金属基复合材料是众所周知的，其基于钛合金粉末与陶瓷粉末的混合物，例如氧化铝粉末，利用低能球磨工艺，随后冷压制和烧结以产生合适的复合材料 。 从现有技术的观点来看，这种现有技术的方法是不利的，即混合物中几乎没有颗粒低于微米尺寸范围，这种缺乏对复合材料的后续加工具有不利影响。 通过在该方法中利用干式高能量强化研磨已经克服了这个问题，其具有在微米尺寸范围内提供必要数量的小颗粒以及提高不同颗粒彼此之间的反应性的效果。 为了生产钛基合金氧化铝金属基体复合材料，将二氧化钛粉末与铝粉末混合并进行干燥的高能量密集研磨，直到分离的颗粒相达到最大500纳米的尺寸。 然后将中间体粉末产物加热以形成其中陶瓷颗粒的平均直径不超过3μm的钛合金/氨基脲金属基质复合物，氧化物由10体积％至小于60体积％的分数组成 的总复合材料。 该复合材料广泛应用于坚韧耐用的工程合金。
