Abstract:
Objective:To investigate the microstructure and mechanical property of titanium parts made by laser solid forming technology. Methods: Titanium parts were made by laser solid forming technology; microstructure and elements were observed by SEM and spectrum analysis. The mechanical property of laser formed titanium and TA2 titanium were measured by Omnipotent testing machine. Results: The microstructure of titanium parts fabricated by laser rapid forming has columnar crystals with regular and epitaxial growth. The inner structure is dense and acicular structure distributed uniform at all field with width about 3-4 ?m; No obvious impurity elements were observed; the tensile-strength and yield strength of titanium parts is obviously superior to the standard of TA2. Conclusion: The microstructure of titanium parts made by laser solid forming can be obviously improved and mechanics performance was greatly improved. Those titanium parts may be used for dental restoration.
