Mechanical testing device equipped with a high temperature furnace

马格德堡奥托-冯-盖里克大学(OvGU)材料和连接技术研究所(IWF)特此申请资助一台新的万能机械试验机，该试验机配备了高温炉，可进行高达1500°C的机械试验和非接触应变测量。新设备将补充IWF现有的研究基础设施。测试机器是各种研究任务所需的，提案中更详细地列出了这些任务。特别是，金属、金属间化合物和陶瓷结构材料和材料复合材料在拉伸、压缩和弯曲模式下的机械行为将被研究到最高温度1500°C。许多研究项目侧重于高温应用材料(目标温度为1000°C到1500°C)，例如难熔金属硅化物材料和金属-陶瓷复合材料。由于这些材料在无涂层状态下容易氧化，因此需要设备齐全的真空室。在非常高的温度下测量(蠕变)应变是具有挑战性的，并且将通过激光引伸仪实现非接触式。

The Institute of Materials and Joining Technology (IWF) at Otto-von-Guericke-University (OVGU) Magdeburg hereby applies for the funding of a new universal mechanical testing machine equipped with a high-temperature furnace for mechanical testing up to 1500 °C and non-contact strain measurement. The new equipment will complement the IWF's existing research infrastructure. The testing machine is required for a variety of research tasks, which are listed in more detail in the proposal. In particular, the mechanical behavior of metallic, intermetallic and ceramic structural materials and material composites in tension, compression and bending modes is to be investigated up to maximum temperatures of 1500 °C. Numerous research projects focus on materials for high-temperature applications (target temperatures of 1000 °C up to 1500 °C), e.g. refractory metal silicide materials and metal-ceramic composites. As these materials are prone to oxidation in the uncoated state, a fully equipped vacuum chamber is requested. The measurement of (creep) strain at very high temperatures is challenging and is to be realized contact-free by means of laser extensometers.
