Abstract

A study of small specimen test techniques applied to examine the mechanical properties of fusion candidate structural material was presented. Tensile and instrumented impact tests were performed with sub-size and standard size specimens, respectively, to evaluate the mechanical properties of China low activation martensitic steel. The ultimate strength and uniform elongation of sub-size specimens were almost equal to those of the standard size specimens at all the three test temperatures. But the sub-size specimens showed slightly higher yield strength than the standard size specimens. With Sokolov method, the calibrated DBTTs obtained for the sub-size Charpy specimens were almost equal to those of the standard size specimens. These results of the sub-size specimens had a good agreement with those of the standard size specimens.
