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.

此次合作的目标是产生有关双金属铸件和金属-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) 加工的 3D 组件所经历的应力场。 具有 3D 晶格结构的铸件制造提供了复杂零件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连接到 MMC 的金属部件组成的气缸实验室样品。 将评估两个系统的机械性能。 在第 2 阶段（第 1 至第 4 年），将使用 FEM 评估不同的网格结构架构。 FEM 结果中最有前途的结构将与第 3 阶段中构建的晶格进行比较。第 3 阶段（第 2 至 4 年）将解决候选晶格和具有不同成分的合金的填充问题：Cr-白铁和碳钢，以及 NiBSi WC 复合材料和碳钢。 随后将进行填充密度、微观结构和磨损的评估。 铸造厂（待定）将用于制造测试组件和样品。 随后，合作伙伴将进行组件的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，两名研究助理将贡献部分时间。 研究生将从广泛的潜在申请者中招募，以确保招募人群的包容性和多样性。
