In the context of this research project in collaboration with the Centre de Metallurgy of Québec, CMQ, General Dynamics-OTS Canada wishes to develop an improved munition casing produced by Powder Metallurgy (PM). The term "improvement" regarding munitions can be defined by different qualifications. In the design process of new munitions, the prediction of the mass and velocity distributions of fragments plays a significant role to optimize the effects and the overall lethality of the munition. Some munition casings produce only a few fragments; however, these fragments have a larger hazardous perimeter resulting in higher collateral damage. For safety purposes, knowledge about fragmentation is essential in conducting risk management. The improvement that will be developed within the project consists of an enhanced fragmentation casing design and the study of a potential production method termed DPR-S, Direct Powder Rolling - Stamping.The selection of a consolidation technique that can i) yield the required mechanical properties, ii) be industrialized for commercialization and iii) reduce material waste is essential. Although different manufacturing methods can achieve the first, they are limited when it comes to scaling up to a profitable industrial production line. Direct Powder Rolling has already been commercialized for large scale production and has been used to produce metal sheets. The novelty of the process being studied is its hybrid nature, DPR-S. The "S" stands for the stamp forming. The microstructure of the DPR-S components plays a roll on the fragmentation behavior of the ammunition components. Therefore, metallurgical characterization will be performed to comprehend the casing state in key regions of the design. This information will be used to execute the fragmentation performance evaluation and better understand the fragmentation behavior. The project will be divided in four phases. - Set-up of pseudo-DPR-S equipment.- Processing of steel alloys by pseudo-DPR-S and sheets by roll-stamping.- Characterization of casings consolidated by pseudo-DPR-S and plates by roll-stamping.- Fragmentation performance evaluation.Regarding the impact of the project, the research and knowledge that will be gained will be applied as part of General Dynamics-OTS Can continued improvement initiative. Possibly achieving a new product that can be commercialized. For the CMQ, the DPR-S method will be developed and used in future projects.

在该研究项目与魁北克中心的CMQ中心合作的情况下，Canada General Dynamics-Outs希望开发由Powder Allallurgy（PM）产生的改进的弹药套管。有关弹药的“改进”一词可以由不同的资格定义。在新弹药的设计过程中，对碎片的质量和速度分布的预测在优化弹药的影响和整体杀伤力方面起着重要作用。一些弹药壳体仅产生几个碎片。但是，这些碎片的危险期较大，导致较高的附带损害。出于安全目的，关于分裂的知识对于进行风险管理至关重要。项目内将开发的改进包括增强的碎片套管设计以及对称为DPR -S的潜在生产方法的研究，直接粉末滚动 - 踩踏。选择合并技术可以i）i）产生所需的机械性能，ii）ii）工业化用于商业化和iii）减少材料废物是必不可少的。尽管不同的制造方法可以达到第一个，但是在扩展到有利可图的工业生产线时，它们受到限制。直接粉末滚动已经被商业化用于大规模生产，并已用于生产金属板。研究过程的新颖性是其混合性质DPR-S。 “ S”代表邮票形成。 DPR-S分量的微观结构对弹药组件的碎片行为发挥作用。因此，将执行冶金表征，以理解设计关键区域的壳体状态。此信息将用于执行碎片性能评估并更好地了解碎片行为。该项目将分为四个阶段。 - 伪-dpr-s设备的设置。-通过滚动板对钢合金处理钢合金。-通过pseudo-dpr-s和盘子合并的套管的表征和滚动板通过滚动板的整合。-碎片性能评估。注册项目的影响，该项目的影响将继续启动。可能会实现可以商业化的新产品。对于CMQ，DPR-S方法将在未来的项目中开发和使用。
