Sinter-forging (SF) is a near-net-shape manufacturing technology that affords high material utilization rates, tight dimensional tolerances, complex product geometries, minimal energy consumption, and maximized mechanical properties. As these traits present favourable techno-economics, this sophisticated approach has been utilized extensively in the cost-effective fabrication of high performance automotive components for nearly five decades. While highly successful, all commercialized SF technologies are presently restricted to the processing of heavy ferrous powders alone. This limitation presents challenges in many automotive scenarios given the recent push towards vehicle light weighting. In this sense, there is a clear global preference for the utilization of light metal alloys as these represent an important means to reduce vehicular weight thereby improving fuel economy and lowering greenhouse gas emissions. To address this technological gap, academics from Dalhousie University and the University of Manitoba will collaborate with engineers at GKN Sinter Metals and the federal research facility CanmetMaterials to develop industrial SF technologies specifically designed for aluminum-based powders. In doing so, autonomous advances developed by the team in prior initiatives will now be unified so as to commission an entirely new family of novel aluminum-based materials specifically designed for SF technology. Focal areas of research

烧结（SF）是一种近网形制造技术，可提供高材料利用率，尺寸紧密的公差，复杂的产品几何形状，最少的能耗和最大化的机械性能。由于这些特征具有良好的技术经济学，因此这种复杂的方法已在近五十年的高性能汽车组件中广泛使用。尽管非常成功，但所有商业化的SF技术目前都仅限于仅处理重金油粉末。鉴于最近推向车辆轻巧的推动力，这种限制在许多汽车场景中都带来了挑战。从这个意义上讲，明显的全球偏爱轻质金属合金是减轻车辆重量的重要手段，从而改善了燃油经济性并降低温室气体的排放。为了解决这一技术差距，Dalhousie大学和曼尼托巴大学的学者将与GKN Sinter Metals和联邦研究机构CanmetMaterials合作开发专门为铝制粉末设计的工业SF技术。这样一来，团队在先前的计划中开发的自主进步现在将被统一，以委托专门为SF技术设计的全新新型铝基材料系列。研究重点领域
