Description

technical field [0001] The invention belongs to the technical field of automobile exhaust systems, and in particular relates to a high-temperature creep test device applied to exhaust systems. Background technique [0002] At present, when the hot-end metal of the automobile exhaust system is working, the temperature can reach more than 900°C. The material is subjected to continuous load under high temperature, and it is prone to problems such as creep failure. With the increase of the exhaust temperature of the national six exhaust products, The service temperature of the silicone lug has also risen, and its high-temperature creep performance is also an indicator that needs to be evaluated under long-term load. [0003] The high-temperature creep testing equipment in the related art is used to test the mechanical properties of materials. In addition to conventional creep and endurance tests, it can also perform stress relaxation tests, high-temperature short-term tensile te...
