| Abstract: | Through experiment,the tensile properties and Vickers hardness of TC4 titanium alloy were tested.The microstructure and tensile fracture were observed by using optical microscope and SEM,researching the reasons of the differences of mechanical properties of TC4 titanium alloy with different microstructures.The result show that the match of strength and plasticity of 3~# sample is the best,comparing the results of the hardness and tensile test of 5~# sample with Wei microstructure,it can be seen that hardnes... |
