| 英文摘要 | In order to analyze the effect of thermal behavior on microstructural evolution in laser deposition manufacturing process, a finite element model was constructed to simulate the temperature field distribution and thermal cycle characteristics. The simulation results show that any node in the substrate and the deposition layer experiences heating or cooling cyclically. And the macro and microstructure of the laser deposited specimen were investigated to determine the evolution of microstructural features in multi-pass deposition layers. The macro and microstructures exhibit epitaxial coarse columnar prior beta grains with basketweave or colony a lamella. The width of alpha lamella changes, and a lamella has basketweave Widmanstatten or colonies Widmanstatten morphology. The line scanning results by energy dispersive spectrometer (EDS) indicate that major alloy elements, Ti, Al, Zr, Mo and V, are distributed uniformly from the substrate to the deposited layer without fluctuation and segregation, suggesting that evolution of microstructure is not the result of segregation but of the heat history. |
