Technological innovation relies on the availability of materials capable of sustaining diverse mechanical,thermal, cyclic or environmental conditions. There is a global shift in the transportation industries towardselectrification of vehicles. To support this innovation, however, novel alloys with currently unavailable mechanical, electrical and thermal properties are required. In this NSERC-Alliance program, a novelmulti-process approach based on advanced powder metallurgy process (Spark Plasma Sintering, SPS) will becombined with a traditional metalcasting process to develop castable Al alloys with graphene-based additives.The proposed research builds on a strong partnership between researchers from The University of BritishColumbia, Nemak Canada (supplier of aluminum (Al) castings to the automotive market) and ZEN GrapheneSolutions Ltd. (mining company and producer of graphene compounds). Graphene is known to have superbmechanical and thermo-electrical properties. However, its integration (much like other nanomaterials) intolarge-scale castings has not been successful to-date. Recent work by the proponents showed, that if the SPS technology is used, graphene-based additives can be efficiently integrated into aluminum castings. As a result, this research program focuses on pioneering industry-driven research consisting of: 1) Identifying optimal graphene additives (e.g., graphene oxide (GO), reduced-GO, pure graphene), 2) SPS processing of graphene containing master alloys, 3) Lab-scale metalcasting experimentation to determine optimal addition levels, casting conditions and blending procedures, and finally, 4) Full-scale manufacture of engine blocks andcylinder heads with graphene-based additives. This research has the potential to fundamentally transform the materials used in the transportation industries. By developing ultralight Al alloys with superb mechanical and thermo-electric properties, Nemak and ZEN will spearhead the Canadian manufacturing and mining sectors in technological innovation, and support the inevitable global shift in the transportation industries towards electric modes of transport.

技术创新依赖于能够维持多种机械，热，环境或环境条件的材料的可用性。运输行业的全球转变朝着车辆的电化。然而，为了支持这一创新，需要具有目前不可用的机械，电气和热性能的新型合金。在这个Nserc-Alliance计划中，一种基于先进粉末冶金过程（Spark等离子体烧结，SPS）的Novelmulti-Process方法将与传统的金属播放工艺结合在一起，以开发具有基于石墨烯的添加剂的可铸造Al合金。拟议的研究以强大的研究为基础不列颠哥伦比亚大学Nemak Canada的研究人员（ALUMINUM（AL）铸件的供应商）与Zen Graphenesolutions Ltd.（采矿公司和石墨烯化合物的生产商）之间的合作关系。已知石墨烯具有超级机械和热电学特性。但是，它的整合（与其他纳米材料一样）插座铸件并未成功。支持者最近的工作表明，如果使用SPS技术，则可以将基于石墨烯的添加剂有效地集成到铝制铸件中。结果，该研究计划的重点是开创性行业驱动的研究，包括：1）识别最佳石墨烯添加剂（例如，氧化石墨烯（GO），减少 - GO，纯石墨烯），2）含有石墨烯的合金的SPS处理， 3）实验室规模的金属播放实验，以确定最佳的加法水平，铸造条件和混合程序，最后4）具有基于石墨烯的添加剂的发动机块和确囊盖的全面制造。 这项研究有可能从根本上改变运输行业中使用的材料。通过开发具有出色的机械和热电特性的超轻AL合金，Nemak和Zen将在技术创新中率领加拿大制造业和采矿领域，并支持运输行业不可避免的全球转移到电动运输方式上。
