- 論文の詳細を見る
Structure and behaviour of carbides precipitated to bond region of stainless steel overlay weld with submerged arc welding was studied. Observations by optical and electron microscopes, electron diffraction, and state analysis of the extracted residues by X-ray diffraction were used. It was determined that carbide precipitated in the boundary between austenite and ferrite had fcc structure and lattice spacing of a_0=10.80A and it was considered to M_23C_6 although distinct conclusion was not given by X-ray diffraction. In order to know distribution of various elements in weld, analysis by ion microanalyzer (IMA) was applied.
