초록

Flat specimens of polycrystal Ni-base superalloy with U-shape notch on both sides were laser cladded by injection of IN738LC powder onto surface. The quality of cladding was investigated by microstructural analysis and high temperature tension test, creep test at 950$^{\circ}C$. Effects of heat treahnent and the angle between the tension axis and the direction of weldment were also investigated.
