Microstructure and Mechanical Properties of Laser Welded Ni-base Superalloy
니켈기 초합금 레이저 용접부의 미세조직과 기계적 특성
Abstract
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
