Grain morphology evolution behavior of titanium alloy components during laser melting deposition additive manufacturing

The compression behavior of Ti–6Al–4V lattice structure with a cell shape of rhombic dodecahedron, which was fabricated by electron beam melting, was investigated at different temperatures. A series of quasi-static compression tests were performed at ambient temperature, 200 °C, 400 °C and 600 °C with a strain rate of 10 −3  s −1 . Two groups of design configurations were adopted by changing the cell size and thickness of struts with the sample size maintained unchanged. The results revealed that their properties varied with different cell sizes and temperatures. Larger cell size leaded to lower modulus and strength of the lattice. Higher temperatures resulted in lower strengths, modulus, densification strains and plateau stresses. The energy absorption of lattice at high temperature was discussed, and the experimental data were compared with aluminum foams, titanium foams and stainless steel lattice. It demonstrated that the rhombic dodecahedron Ti–6Al–4V lattice structure could be applied as load-bearing components and energy absorber at high temperature.

Microstructure evolution of sub-critical annealed laser deposited Ti–6Al–4V alloy

The dynamic properties of TiC particulate-reinforced titanium matrix composites (TiCp/Ti) prepared by pre-treatment melt process at elevated temperatures were characterized and tested by using split Hopkinson tensile bar (SHTB). The tensile properties of these materials were investigated to determine all the parameters of the Johnson–Cook constitutive mode. By considering the strain hardening and the coupled effects of temperature and strain rate, a modified Johnson–Cook constitutive model was proposed to predict the dynamic behavior of TiCp/Ti. The model predictions are in good agreement with the experimental results, which indicates that the modified model can be used to describe the flow stress for the studied composite at elevated temperatures.
