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各种机械、热、循环或环境条件的材料的可用性。全球交通运输行业正朝着车辆电气化的方向转变。然而，为了支持这一创新，需要具有目前无法获得的机械、电气和热性能的新型合金。在这个nserc联盟项目中，一种基于先进粉末冶金工艺（火花等离子烧结，SPS）的新型多工艺方法将与传统的金属铸造工艺相结合，以开发含有石墨烯基添加剂的可浇注铝合金。这项拟议的研究建立在英属哥伦比亚大学、加拿大Nemak（汽车市场铝（Al）铸件供应商）和ZEN GrapheneSolutions Ltd.（石墨烯化合物的采矿公司和生产商）的研究人员之间强有力的合作伙伴关系之上。众所周知，石墨烯具有超机械和热电性质。然而，它的集成（非常像其他纳米材料）到目前为止还没有成功的大规模铸件。支持者最近的工作表明，如果使用SPS技术，基于石墨烯的添加剂可以有效地集成到铝铸件中。因此，该研究项目侧重于开创性的行业驱动研究，包括：1)确定最佳石墨烯添加剂（例如氧化石墨烯（GO），还原氧化石墨烯，纯石墨烯），2)含石墨烯母合金的SPS加工，3)实验室规模的金属铸造实验，以确定最佳添加水平，铸造条件和混合程序，最后，4)石墨烯基添加剂的发动机缸体和气缸盖的全面生产。这项研究有可能从根本上改变运输行业使用的材料。通过开发具有卓越机械和热电性能的超轻铝合金，Nemak和ZEN将引领加拿大制造业和采矿业的技术创新，并支持全球运输行业向电动运输方式的不可避免的转变。
