The sound velocity increased with increasing strain in the elastic　deformation, and then decreased with increasing plastic strain during tensile testing. From a　relation between the sound velocity and the elastic strain, the acousto-elastic constant was　calculated to be 8.5×10-6 MPa-1. The surface roughness and the hardness were measured for　specimens taken out from testing machine after required strain. The peak intensity of the bottom echo spectrum and the average gradient of the transfer function (AGTF) obtained from　the bottom echo spectrum decreased with increasing plastic strain. The decrease in the　ultrasonic parameters was explained  rom the change in the dislocation density and arrangement　by using Granato and Luecke string model. The peak frequency of the bottom echo spectrum　did not change with increasing plastic strain. The ultrasonic parameters were measured　off-line with specimens taken out from testing machine after required strain by the conventional　immersion method, and decreased with increasing plastic strain as those obtained in real-time.　When specimens were annealed, the hardness continuously decreased with increasing annealing　time, and the yield strength and the sound velocity slightly increased after smaller annealing time, and then decreased with increasing annealing time. For annealed specimens, the peak　intensity and AGTF obtained by the real-time measurement also decreased with increasing　plastic strain, and the rates of the ultrasonic parameters increased with increasing annealing　time.", "subitem_description_type": "Abstract"}]}, "item_119_description_29": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"subitem_description": "text",
