Based on the current state of technology and research, the members of the TU Clausthal, RWTH Aachen and TU Bergakademie Freiberg have set up a research group to look at the minimisation of the process steps in the production of titanium in a complex and interdisciplinary way. The main motivation behind the Research Unit is the dramatically increasing problem of diminishing sources of energy and increasing emissions, which drastically challenges the current perceptions on individual mobility and that demands entirely new traffic concepts with a clearly higher content of lightweight designs. It is the overall objective of the Research Unit to establish scientific foundations for a process with minimised steps, which can be implemented on a large industrial scale, for the production of inexpensive titanium materials as an alternative to the existing titanium technology. The project is to include everything from the conditioning of inexpensive raw materials, metal recovery and processing to the development of materials. The subgoals of the Research Unit are: (1) utilisation of potential reserves of raw materials; (2) direct recovery of titanium and titanium alloys from their raw materials without the TiCl4 detour; (3) minimisation of the number of process steps; (4) minimisation of the energy input; (5) use of new refractory ceramics for the smelters; (6) processing by means of conversion and joining as feedback for the metallurgical process steps; (7) development of suitable alloy systems; (8) efficient recycling of titanium scrap. In addition to the actual process development, the Research Unit wants to trigger future research activities in the fields of the production, processing and development of titanium materials by providing fundamental data. The research project is forecasted to include two phases of three years each. During the first phase, laboratory investigations are to show that the concepts, on which this project is based, are feasible. The proof will consist of titanium metal produced with minimised process steps from various process routes. This precursor material will be processed into low grade, technical grade, and high grade materials, which will be characterised in terms of their production and usage properties. At the same time, suitable alloy systems will be developed. The second phase will then include the transfer to the pilot plant scale with the cooperation of the titanium producing and processing industries. Other departments may join the Research Unit during this phase and additional international cooperation may be established.

基于当前的技术和研究状况，克劳斯塔尔工业大学、亚琛工业大学和弗赖贝格工业大学的成员成立了一个研究小组，以复杂和跨学科的方式研究钛生产过程中工艺步骤的最小化。研究单位背后的主要动机是能源减少和排放增加的问题急剧增加，这极大地挑战了目前对个人移动性的看法，并要求全新的交通概念，具有明显更高的轻量化设计内容。研究单位的总体目标是为步骤最少的工艺建立科学基础，该工艺可以在大工业规模上实施，用于生产廉价的钛材料，作为现有钛技术的替代品。该项目将包括从廉价原材料的调节、金属回收和加工到材料开发的所有内容。该研究单位的次级目标是：（1）利用潜在的原材料储备;（2）直接从原材料中回收钛和钛合金，而不需要TiCl 4绕道;（3）最大限度地减少工艺步骤的数量;（4）最大限度地减少能源投入;（5）在冶炼厂使用新的耐火陶瓷;（6）在冶炼厂使用新的耐火陶瓷。（6）通过转化和连接作为冶金工艺步骤的反馈进行加工;（7）开发合适的合金系统;（8）有效回收钛废料。除了实际的工艺开发外，研究部门还希望通过提供基础数据，在钛材料的生产，加工和开发领域开展未来的研究活动。该研究项目预计将包括两个阶段，每个阶段为期三年。在第一阶段，实验室调查将表明该项目所依据的概念是可行的。该证明将包括钛金属生产与最小化的工艺步骤，从各种工艺路线。这种前体材料将被加工成低级，技术级和高级材料，这些材料将根据其生产和使用特性进行表征。与此同时，将开发合适的合金系统。第二阶段将包括在钛生产和加工行业的合作下转移到试验工厂规模。在这一阶段，其他部门可以加入研究股，并可能建立更多的国际合作。
