[105] Melting behavior of Si during laser irradiation for Al-Si alloy

*Masaki MATSUNO1, Kohei MORISHITA2, Hirofumi MIYAHARA2 (1. Kyushu Univ.(M1), 2. Kyushu Univ.)

Keywords:レーザ、Al-Si合金、その場観察、放射光X線イメージング、等軸晶

レーザ粉末床溶融結合法においてAl-Si合金は溶融池の境界近傍で等軸晶を形成する.本研究では放射光X線イメージングを用いて急速溶解・急速凝固現象のその場観察を行いAl-Si合金の凝固組織形成過程の議論を行った.
