This NSERC-CRD grant application seeks to enable a collaboration between the metalcasting and materials development research groups at the University of British Columbia (UBC) and Unicast Inc. The research teams seek to jointly work on developing a fundamental scientific understanding of the behavior of high manganese (Mn) steels currently used for diverse mining, rock crushing and processing applications. Building on the fundamental knowledge, the research team will explore the use of new additives and alloy compounds to further enhance the mechanical performance and control the microstructure of new steel alloys. Unicast Inc. is Canada's leader in the manufacture of manganese steel castings for diverse technological systems and applications. Since the currently available Mn steel alloys are reaching their performance limits, it is essential that new R&D into material development and characterization is undertaken. In this regard, Unicast Inc. and UBC will jointly study, fabricate and test new Mn-steel alloys at UBC's metalcasting laboratory and characterization facilities. A baseline material (ASTM A128 Grade A) will be used for all experiments. The composition of this baseline material will then be varied with suitable addition of manganese, chromium (Cr) and molybdenum (Mo). The goal of these additives is to enhance the mechanical performance of the alloy, toughness and abrasion resistance. Further, the feasibility of successfully incorporating Titanium Carbide (TiC) inserts in the matrix material will be also examined. The research outcomes are expected to yield alloys with superior performance, which in turn will benefit many mining operations (from crushers, to rock sizers, to pulverizers used in the cement industries). With superior and technological advantage, Unicast Inc. will be able to support the Canadian manufacturing and mining industries to achieve enhanced efficiency (less down-time) and improved economy of operations. This CRD program also offers outstanding opportunities for students to be trained in R&D related to materials development for several of Canada's key sectors.

该NSERC-CRD赠款申请旨在使不列颠哥伦比亚大学（UBC）（UBC）和Unicast Inc. Metalcasting与材料开发研究小组之间进行合作。研究团队旨在共同致力于建立对高知名行为的基本科学理解锰（MN）钢目前用于不同的采矿，岩石压碎和加工应用。在基本知识的基础上，研究团队将探索使用新添加剂和合金化合物的使用，以进一步增强机械性能并控制新钢合金的微观结构。 Unicast Inc.是加拿大为各种技术系统和应用制造锰钢铸件的领导者。由于当前可用的MN钢合金已达到其性能限制，因此必须进行新的研发和表征。在这方面，Unicast Inc.和UBC将在UBC的Metalcasting实验室和表征设施中共同研究，制造和测试新的MN钢合金。所有实验将使用基线材料（ASTM A128级A）。然后，该基线材料的组成将通过合适的锰，铬（CR）和钼（MO）而变化。这些添加剂的目的是增强合金，韧性和耐磨性的机械性能。此外，还将检查成功地将碳化钛（TIC）插入物插入基质材料的可行性。 预计研究结果将产生具有出色性能的合金，从而使许多采矿作业（从压碎机，岩石塞人到水泥行业使用的粉碎机）受益。凭借卓越和技术优势，Unicast Inc.将能​​够支持加拿大制造业和采矿行业，以提高效率（较少的停机时间）和改善的运营经济。该CRD计划还为学生提供了与加拿大几个关键部门的材料开发有关的研发培训的出色机会。
