The goal of this partnership is to generate new knowledge on the processing, microstructure and properties of a bi-metal casting and metal-metal matrix composite (MMC) castings. The stress field experienced by a 3D component processed for Castings and Additive Manufacturing (AM) of lattice structures will be evaluated using Finite Element Modelling (FEM). Manufacturing of the castings with 3D lattice structures provides freedom of design and manufacture of complex parts. The research will be carried out in three phases. Phase 1 (years 1 and 2) will be the processing of laboratory samples of cylinders composed of a bi-metallic part, and a metallic part joined to an MMC. The mechanical properties of both systems will be evaluated. In Phase 2 (years 1 to 4), different lattice structural architectures will be evaluated using FEM. The most promising structure from FEM results will be compared with built lattices in Phase 3. Phase 3 (years 2 to 4) will address the filling of the candidate lattice and alloy with varying compositions: Cr-white iron and carbon steel, and NiBSi with WC composite and carbon steel. Subsequent evaluation of fill density, microstructure, and wear will be carried out. A foundry (TBD) will be used to make test components and samples. This will be followed by microstructural characterization of the component and field testing by the Partner. For HQP, two graduate students will be recruited for the project and partial time of two Research Associates will contribute. The graduate studetns will be recruited from a wide pool of potential applicants in order to ensure inclusivity and diversity of the recruited population.

该合作伙伴关系的目标是产生关于双金属铸件和金属-金属基复合材料（MMC）铸件的加工、微观结构和性能的新知识。 将使用有限元建模（FEM）评估为晶格结构的铸件和增材制造（AM）处理的3D组件所经历的应力场。 具有3D网格结构的铸件的制造提供了复杂部件的设计和制造的自由度。 研究将分三个阶段进行。 第1阶段（第1年和第2年）将处理由双金属部件和与MMC连接的金属部件组成的气缸的实验室样品。 将评价两种系统的机械性能。 在第二阶段（第1年至第4年），将使用有限元法对不同的网格结构体系进行评估。 在第3阶段，将从FEM结果中获得的最有希望的结构与构建的网格进行比较。 第3阶段（第2年至第4年）将解决候选晶格和不同成分合金的填充问题：Cr-白口铁和碳钢，以及含WC复合材料和碳钢的NiBSi。 随后将对填充密度、微观结构和磨损进行评估。 将使用铸造厂（TBD）制造测试组件和样品。 随后，合作伙伴将对部件进行微观结构表征和现场测试。 对于HQP，该项目将招募两名研究生，两名研究助理的部分时间将做出贡献。 研究生将从广泛的潜在申请人中招募，以确保招募人口的包容性和多样性。
