High Speed Dilatometry for Dynamic Behavior Analysis of Advanced Materials during Manufacturing and Service

我们提议收购西塔工业公司DIL-III淬火应变仪用于测量金属样品在高加热/冷却速率（加热时高达2000 K/秒，控制冷却时高达500 K/秒）下表现出的应变，并用于测试材料对热冲击的响应。此外，该设备将允许测试暴露于严重和周期性热循环和热冲击的部件，如月球车。加拿大只有一台淬火温度计，它位于汉密尔顿的CANMET，需要这种基础设施的26名麦吉尔学员很难到达。DIL-III淬火温度计是一种使用感应加热来快速加热样品和快速冷却高速气体的装置。这种配置将是有用的，以保持SPS巩固过程中的进展，开发先进的焊接工艺的结构和航空航天应用，制造新材料，使用快速淬火计划，并有助于发展的分析工具，用于测量局部应变和应力，使用电子束EBSD技术。所要求的基础设施将配备低温选项，以便能够进行低至-150 ℃的测量，用于研究月球车等外层空间应用材料的热循环和抗热震性。对这种设备的需求实际上是如此迫切，以至于麦吉尔工程学院的五位教授组成的团队已经要求它。申请者实验室的26名实习生将立即离开仪器，预计来自其他部门，周围机构和研究中心（NRC）以及行业的许多其他HQP（航空航天、焊接、金属制造）将成为常规用户。

We propose the purchase of a Theta Industries Inc. DIL-III quench dilatometer to measure strain exhibited by metallic samples during high heating/cooling rates (up to 2000 K/sec in heating and 500 K/sec in controlled cooling) and for the testing of the response of material to thermal shock. Moreover, the equipment will allow for the testing of components exposed to severe and cyclic thermal cycling and thermal shock, such as the lunar rover. There is only one quench dilatometer in Canada, and it is located at CANMET, Hamilton, which is hardly accessible to the twenty-six McGill trainees in need of this infrastructure. The DIL-III quench dilatometer is a unit using induction heating to quickly heat-up the samples and high velocity gases for rapid cool down. This configuration will be useful to maintain progress in SPS consolidation processes, to develop advanced welding processes for structural and aerospace applications, to manufacture new materials using rapid quench schedules and to contribute to the development of analytical tools for the measurement of localized strain and stress using e-beam EBSD technique. The requested infrastructure will be equipped with a cryogenic option, allowing for measurements down to -150C for the study of thermal cycling and thermal shock resistance of materials for outer space applications, such as the lunar rover. The need for this equipment is actually so urgent that a team of five professors from the McGill Faculty of Engineering has grouped to request it. Twenty six trainees in the applicants' laboratories will immediately beneficiate from the instrument, and it is expected that many other HQPs from other departments, surrounding institutions and research centers (NRC), and industries (aerospace, welding, metal manufacturing) will become regular users.
