Titanium (Ti) and its alloys represent superior light metal alternatives in the pursuit of automobile weight reduction and increased performance. However, to date Ti's use in the automotive industry has been restricted to luxury vehicles due to the high costs of Ti production and mill product manufacturing. This research program seeks to establish a low cost method of producing titanium parts for automotive applications through the development of novel processes across the entire process stream. The research program is structured into seven themes including; Ti powder production (theme I), sintering fundamentals (theme II), sintering of TiAI intermetallics (theme III), "press and sinter" developments (theme IV), mechanical testing (theme V), asymmetric roll compaction (theme VI) and prototyping development and evaluation. These themes will focus on both commercially pure Ti and Ti alloy components. Automotive exhaust systems and engine intake and exhaust valves will be the applications targeted by the prototyping activities. The two supporting industrial partners, Kingston Process Metallurgy Inc. (KPM) and Wescast Industries Inc (Wescast), will work in close collaboration with academic partners at Dalhousie and Queen's University to execute the project. When completed, this project will deliver a scaled-up method for producing low cost Ti pOWder, allowing KPM to further develop a pilot plant with the aim of establishing a new commercial powder production process. This project will also establish a novel and optimized Ti based powder metallurgy (PM) parts manufacturing process, enabling Wescast to develop a pilot plant production operation based on automotive Ti. The inclusion of high performance, low cost Ti components in their product line will allow Wescast to expand their operations and maintain a competitive advantage in the automotive industry. Replacing steel counterparts with Ti alternatives will typically result in a 50% weight reduction on a component basis. In the particular case of exhaust systems, a 50% worldwide market penetration by Ti could result in a green house gas reduction of 1.5 mega tonnes per year. Therefore the successful completion of this project will make a positive contribution to the Canadian Automotive industry, the Canadian economy and the environment.

钛（Ti）及其合金代表了追求汽车轻量化的上级轻金属替代品 并提高性能。然而，到目前为止，钛在汽车工业中的使用仅限于豪华汽车 这是由于钛生产和轧制产品制造的高成本。这项研究计划旨在建立一个低 通过开发新工艺生产汽车用钛部件的成本方法 整个流程。该研究计划分为七个主题，包括：钛粉生产 （主题一）、烧结基础（主题二）、TiAl金属间化合物烧结（主题三）、“压制和烧结”发展 （专题四）、机械测试（专题五）、不对称碾压（专题六）和原型开发， 评价这些主题将重点关注商业纯钛和钛合金组件。汽车排气系统 和发动机进排气门将是原型活动的目标应用。 两个支持工业合作伙伴，金斯顿过程冶金公司。(KPM)关于Wescast Industries Inc （Wescast）将与达尔豪西和女王大学的学术合作伙伴密切合作， 项目完成后，该项目将提供一种生产低成本Ti粉的扩大方法，使KPM能够 进一步开发一个试验工厂，目的是建立一种新的商业粉末生产工艺。该项目将 还建立了一个新的和优化的钛基粉末冶金（PM）零件制造工艺，使Wescast 开发基于汽车钛的中试工厂生产操作。采用高性能、低成本钛合金， 组件在其产品线将使Wescast扩大其业务，并保持竞争优势， 汽车行业 用钛替代品取代钢对应物通常会导致部件重量减少50%。 在排气系统的特定情况下，Ti的50%的全球市场渗透率可能导致绿色家用气体 每年减少150万吨。因此，该项目的成功完成将使积极的 为加拿大汽车工业、加拿大经济和环境做出贡献。
