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.

我们提议收购Theta工业公司。DIL-III型淬火膨胀仪，用于测量金属样品在高加热/冷却速率下（加热高达2000k /秒，控制冷却高达500k /秒）所表现出的应变，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循环热循环和热冲击的组件，如月球车。加拿大只有一个淬灭膨胀仪，它位于汉密尔顿的CANMET，对于需要这种基础设施的26名麦吉尔实习生来说，这是很难接近的。dili - iii猝灭膨胀仪是一种使用感应加热快速加热样品和高速气体快速冷却的装置。这种配置将有助于保持SPS固结过程的进展，开发用于结构和航空航天应用的先进焊接工艺，使用快速淬火计划制造新材料，并有助于开发用于使用电子束EBSD技术测量局部应变和应力的分析工具。所要求的基础设施将配备低温选项，允许测量低至-150C，用于研究外太空应用（如月球车）材料的热循环和热冲击抗逆性。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了一个团队，要求提供这种设备。申请人实验室的26名学员将立即受益于该仪器，预计其他部门，周边机构和研究中心（NRC）以及行业（航空航天，焊接，金属制造）的许多其他hqp将成为常规用户。
