| Research Abstract |
The microstructure evolution in weld metal was clarified by the in-situ observation techniques and the guiding principles was proposed to develop a material having excellent properties and contribute to the production technology research of high strength welded structure .
The nano-oxide utilization technology was established by summarizing the results systematically along the welding thermal cycle, as analyzed each molten metal, solidification, solid-phase transformation, visualization of particle aggregation and dispersion behavior, the development of the molten pool simulation model, and elucidation of the solid-phase transformation mechanism.
