钛的密度约为低碳钢的45%,单质钛金属的强度不是很高,通常采用合金化的方法提高其强度。大约50年前,冶金专家们在钛中添加铁、钒和铝,在适当的条件下制成了强度很高的Ti185合金。但是这种材料倾向于成团聚集,铁元素可能会聚集于一些区域,在材料中形成一些缺陷,难以形成稳定的商业化的生产。大约6年以前,针对这个问题,美国能源部太平洋西北国家实验室等单位创新地开发出一种低成本的产业化的生产技术。在制备Ti185合金时,工艺流程不是首先从熔化态的钛金属开始,而是以氢化钛粉作为进料,
The density of titanium is about 45% of low-carbon steel, elemental titanium metal is not very high strength, usually by alloying to increase its strength. About 50 years ago, metallurgists added iron, vanadium and aluminum to titanium to make high-strength Ti185 alloys under the right conditions. However, this material tends to agglomerate, and iron may accumulate in some areas, causing some defects in the material, making it difficult to form a stable, commercialized production. About six years ago, in response to this issue, the United States Department of Energy Pacific Northwest National Laboratory and other units innovatively developed a low-cost industrial production technology. In the preparation of Ti185 alloy, the process does not start with the molten titanium metal, but with titanium hydride powder as feed,
