Microstructure-Mechanical Property Relationships for Engineering Alloys

申请人的研究计划的总体目标是开发有关工程合金的机械行为的基础知识，并将这些知识应用于工业过程和应用。该提案专门解决了缺乏知识的问题，这些知识阻碍了工程合金在其应用中的最佳使用。具体而言，该提案侧重于i）原子团簇强化铝合金强度的起源，ii）开发新方法以找到镁合金的最佳化学成分，iii）开发在工业条件下应用镁合金所需的实验数据和数学模型（即多轴变形条件）和iv）研究超声波在工程合金中的传播，使得可以开发新的传感器来定量测量热处理期间的微观结构演变（最终成为一种可以在工业中应用的工具）。** 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。这些改进的合金将允许i）由于车辆重量轻而减少的排放（减少汽车、卡车、飞机和船舶的燃料消耗），ii）改进的车辆安全性（例如更好的碰撞性能）和iii）更有效和更安全的能量运输系统（例如天然气和石油管道）。最后，该提案将支持6-7名受过高等教育的工程师和科学家的教育，这些工程师和科学家是加拿大工业，大学和政府实验室的高需求。

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.
