Microstructure-Mechanical Property Relationships for Engineering Alloys

申请者研究计划的总体目标是发展工程合金机械行为的基本知识，并将这些知识应用于工业过程和应用。这项建议具体解决了缺乏知识的问题，阻碍了工程合金在应用中的最佳使用。具体地说，该建议侧重于i)原子团簇强化铝合金的强度来源，ii)开发寻找镁合金最佳化学成分的新方法，iii)开发在工业条件下(即多轴变形条件)应用镁合金所需的实验数据和数学模型，以及iv)研究超声波在工程合金中的传播，以便开发新的传感器来定量测量热处理过程中的组织演变(最终成为可应用于工业的工具)。**这项工作的影响涉及运输和能源部门对新的改进合金的需求。这些改进的合金将有助于i)由于车辆的轻量化而减少排放(汽车、卡车、飞机和轮船的燃料消耗减少)，ii)提高车辆的安全性(例如，更好的碰撞性能)，以及iii)更高效和更安全的能源运输系统(例如，天然气和石油管道)。最后，这项提议将支持加拿大工业、大学和政府实验室对6-7名受过高等教育的工程师和科学家的教育。

The overall objective of the applicant's research program is to develop basic knowledge on the mechanical behaviour of engineering alloys and the application of this knowledge to industrial processes and applications. This proposal specifically addresses problems where there is a lack of knowledge which hinders the optimal use of engineering alloys in their application. Specifically, the proposal focuses on i) the origin of strength in aluminum alloys strengthened by atomic clusters, ii) the development of new approaches to find optimal chemical compositions for magnesium alloys, iii) the development of experimental data and mathematical models needed to apply magnesium alloys in conditions found in industry (i.e. multiaxial deformation conditions) and iv) to study the propagation of ultrasonic waves in engineering alloys so that new sensors can be developed to quantitatively measure microstructure evolution during heat treatment (ultimately a tool that can be applied in industry). **The impact of the work relates to the need for new improved alloys in the transportation and energy sectors. These improved alloys will allow for i) reduced emissions due to light weighting of the vehicles (reduced fuel consumption in automobiles, trucks, airplanes and ships), ii) improved safety of vehicles (e.g. better crash performance) and iii) more efficient and safer energy transportation systems (e.g. gas and oil pipelines). Finally, this proposal will support the education of 6-7 highly educated engineers and scientists which are in high demand from Canadian industry, universities and government laboratories.
