The heating under A1 transformation point (600℃) did not affect the material properties of weld metal, HAZ and base metal regardless of cooling process. The heating over A3 transformation point (900℃) and the water cooling from it caused the hardening and the reduction of Charpy absorbed energy. The degree of them was larger in the base metal rather than in the weld metal because it depended on the amount of carbon.}, pages = {819--824}, title = {加熱・冷却された構造用鋼溶接部の材料特性に関する基礎的研究}, volume = {21}, year = {2013} }
