钛合金与碳纳米复合材料的制备及力学性能的研究
Preparation and mechanical properties of titanium alloy and carbon nanocomposites
摘要
Abstract
To investigate the effects of forming process and temperature environment on the mechanical properties of titanium alloy and carbon nanotube composite(CNTs/Ti),this study modifies the surface of the titanium alloy ma-terial with carbon nanotubes.The CNTs/Ti powder is prepared by the wet ball milling method,and the tensile speci-mens are prepared by the selective laser melting technology.Subsequently,the tensile mechanical properties of CNTs/Ti are systematically studied under different temperature environments.The results show that when the ball milling time is 5 hours,the content of element C significantly increases to 22.78at%.At-58℃,the specimen with a CNTs content of 0.6wt‰ has the highest tensile strength.The trend under the low-temperature cycle is the same as that at low temperature(-58℃).At 600℃,the specimen with a CNTs content of 0wt‰ has the highest tensile strength.By observing the fracture surface of the specimens,it is found that the specimens still maintain high plastici-ty at-58℃and 600℃.关键词
