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拨款申请旨在使不列颠哥伦比亚省大学（UBC）的金属铸造和材料开发研究小组与Unicast Inc.研究团队寻求共同努力，对目前用于各种采矿，岩石破碎和加工应用的高锰钢的行为进行基本的科学理解。在基础知识的基础上，研究团队将探索使用新的添加剂和合金化合物，以进一步提高机械性能并控制新型钢合金的微观结构。 单播公司是加拿大领先的制造锰钢铸件的各种技术系统和应用。由于目前可用的Mn钢合金正在达到其性能极限，因此必须进行新的材料开发和表征研发。在这方面，Unicast Inc.和UBC将在UBC的金属铸造实验室和表征设施共同研究、制造和测试新的锰钢合金。基线材料（ASTM A128 A级）将用于所有实验。然后通过适当添加锰、铬（Cr）和钼（Mo）来改变该基线材料的组成。这些添加剂的目的是提高合金的机械性能、韧性和耐磨性。此外，还将研究成功地将碳化钛（TiC）插入基体材料中的可行性。 预计研究成果将产生具有上级性能的合金，这反过来将使许多采矿作业受益（从破碎机到岩石筛分机，再到水泥工业中使用的粉碎机）。Unicast Inc.凭借其上级和技术优势，将能够支持加拿大的制造业和采矿业，以提高效率（减少停机时间）和改善运营经济性。该CRD计划还为学生提供了出色的机会，可以在加拿大几个关键部门的材料开发相关的研发方面进行培训。
