PROBLEM TO BE SOLVED: To provide a unit for evaluating material strength of a thin metal plate, the unit being suitable for high-temperature creep test or tensile test of a thin metal plate.SOLUTION: A unit 1 for evaluating high-temperature creep strength comprises a tabular test piece 2 and a pair of fixing jigs 3 for attaching the test piece 2 to a chuck of a test device. The thin test piece 2 and the jigs 3 are configured to be integrally fixed by a fixing pin 4. The test piece 2 has shoulders 22 fitted to and stored in shoulder fitting grooves 34 of the jigs 3 and has a parallel part 21 partially fitted to and stored in a slit 33. In this state, the fixing pin 4 is inserted to a through hole 25 to have the position fixed, whereby the unit 1 for evaluation is configured. Next, the unit 1 is erected, and upper and lower ends of a grip 31 is engaged with and fixed to a pull rod 5 of the test device. Further, ring-shaped projections 35 of the upper and lower jigs 3 are fixed to an upper jig 6a and a lower jig 6b of a jig 6 for measurement, respectively. After the completion of attachment, the parallel part 21 in the unit 1 is stored in an electric oven 7. |
