Design Of Test System Of Minitype Specimen High Temperature Creep

Based on the sum-up of the research history and latest development of creep test technology, a new creep test method, namely minitype specimen creep testing method, is investigated in this paper. Design of minitype specimen, research of current heating method and design of minitype specimen creep test device are emphases of this paper. Creep test of 12Cr1MoV steel by this method proved that the method is feasible and available. Results of the research prove the following:1. Minitype specimen high temperature creep test can reflect the course and rule of creep, and test data are stable.2. Using the method of current heating in the course of creep, there are many excellences as following: Complexity of creep test device can be minished. Labor intension is weakening, speed of heating is easy to control. Period of test is reduced. Current heating method is economic than traditional heating method about 59%.
