概要

論文の詳細を見る
The thermal residual strain at the internal position of the materials was measured nondestructively by neutron diffraction. The diffractometers, RESA at JAERI and Sirius at KEK were used. The three-layers joint materials of sintered hard alloy and normal metal made by Self-propagating High-temperature Synthesis and the S45C round bar hardened by induction heating were measured. The results obtained by the measurements are discussed precisely. The difference of the characteristic of the two diffractometers was also discussed.
