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的是生成有关双金属铸件和金属金属基质复合（MMC）铸件的处理，微观结构和特性的新知识。 将使用有限元建模（FEM）评估用于铸件的3D组件经历的应力场（AM）。 用3D晶格结构制造铸件提供了复杂零件的设计和制造自由。 该研究将分为三个阶段。 第1阶段（第1和2年）将是由双金属部分组成的圆柱体的实验室样品，以及与MMC相连的金属部分。 将评估两个系统的机械性能。 在第2阶段（1至4年）中，将使用FEM评估不同的晶格结构结构。 FEM结果最有希望的结构将与第3阶段中的建筑格局进行比较。第3阶段（2至4年）将介绍候选晶格和合金具有不同组成的填充：CR-White铁和碳钢，以及WC复合材料和碳钢的NIBSI。 随后将对填充密度，微结构和磨损进行评估。 铸造厂（TBD）将用于制作测试组件和样品。 随后，合作伙伴对组件和现场测试的微结构表征。 对于HQP，将为该项目招募两名研究生，两名研究助理的部分时间将贡献。 研究生Studetn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。
