This project aims at evaluating the suitability of the advanced rheology-based measurement techniques for the improvement of flowability of water-atomized metallic powders and powder mixtures. These powders and powder mixtures serve as a feedstock for rapidly developing advanced manufacturing processes, such as the high processing speed compaction (PM), additive manufacturing via the laser powder-bed fusion and the binder-jetting techniques (AM), and the metal injection molding (MIM). The improvement of flow properties of these powders and powder mixture will allow fabrication of high performance products for transport and energy.Furthermore, the realization of this project will position our industrial partner as one of the largest suppliers of cost-effective steel powders to Canadian companies which turn towards PM, AM and MIM technologies with the objective to augment their overall competitiveness.A combination of cost-effective water-atomized powders with an improved buy-to-fly ratio and high in-process powder recycling rate of PM/AM/MIM manufacturing technologies would benefit both the industry and the environment.Finally, this research project will contribute to form highly qualified technical personnel trained in the fields of materials science and advanced manufacturing to satisfy the ever-growing demand from Canadian manufacturing industry.

该项目旨在评估先进的基于流变学的测量技术对改善水雾化金属粉末和粉末混合物流动性的适用性。这些粉末和粉末混合物用作快速发展的先进制造工艺的原料，例如高加工速度压实（PM），通过激光粉末床熔融和粘合剂喷射技术（AM）的增材制造，以及金属注射成型（MIM）。这些粉末和粉末混合物的流动性能的改善将允许制造用于运输和能源的高性能产品。此外，该项目的实现将使我们的工业合作伙伴成为加拿大公司转向粉末冶金的最大成本效益钢粉供应商之一，AM和MIM技术，以提高其整体竞争力。具有成本效益的水雾化粉末与改进的购买飞行比和高的提高粉末冶金/粉末冶金/金属注射成形制造技术的工艺粉末回收率将有利于工业和环境的发展，最终，本研究项目将有助于培养高素质的材料科学和先进制造领域的技术人才，以满足加拿大制造业日益增长的需求。
