Study on the Microstructure and Tensile Properties of TiC/TC4 Functionally Gradient Materials by Laser Melting Deposition

doi:10.3901/JME.2024.19.356

Abstract

Abstract: Functionally graded material (FGM), which have customized chemical composition or microstructure, are capable of meeting the service requirements in multidimensional harsh environments.Therefore, it can be applied in components such as aerospace parts and engine turbine blades.The laser melting deposition (LMD) process, which uses powder feed to melt and solidify layer by layer, is a novel method to dynamically mix multiple materials and change the microstructure within the three-dimensional volume.TiC / TC4 FGM were prepared using the LMD process, and the microstructure and mechanical properties were characterized using scanning electron microscopy, electron backscatter diffraction, and tensile tests.The results shows that the phase compositions of different gradient layers were TiC, α-Ti, and β-Ti, and the types of phases did not change significantly with the TiC content.The morphology of TiC in the FGM changes from coarse dendritic crystals + unmelted TiC at the top to granular nascent TiC + undeveloped dendritic crystals, chain-like TiC + granular-like TiC + rod-like TiC at the bottom.With the increase in gradient, the strength of the FGM initially increases and then decreases, while the elongation at fracture continuously decreases.Cracks preferentially form and propagate in the dendritic grains and undissolved TiC phases.The in-situ TiC makes a greater contribution to improving the strength of the material, and the strengthening mechanisms are mainly grain boundary strengthening and load transfer strengthening.
