抄録

The effect of transformation expansion on the restraint stress was investigated by numerical simulation. A RRC-type weld joint with y-slit groove were used for the calculation of restraint stress. The transformation temperature Ms of weld metal and the restraint intensity <I>R</I><sub>F</sub> of the joint were varied systematically. The lower the transformation start temperature <I>M</I><sub>s</sub> is, the lower the restraint stress <I>σ</I><sub>w</sub> at room temperature becomes. The higher the restraint intensity <I>R</I><sub>F</sub> is, the lower the restraint stress <I>σ</I><sub>w</sub> at room temperature becomes.
