Abstract
The mechanical properties of laser solid forming (LSF) of Ti-Al-V ternary system titanium alloys from blended elemental powders are investigated. The relationship between the composition and the hardness of LSF Ti-xAl-yV(x≤10, y≤25) is obtained based on the hardness test and the neural network model optimization. The room temperature tensile properties of some typical LSF Ti-xAl-yV alloys are obtained, and the scale factor K of the tensile strength to the microhardness is obtained between 2.86 to 3.00, and thus the tensile strength prediction for LSF Ti-xAl-yV can be realized. The test results show that the room temperature tensile properties of laser deposited Ti-4Al-3V, Ti-5Al-3V, Ti-4Al-4V, Ti-5Al-4V and Ti-3Al-6V have reached the wrought standard of Ti-6Al-4V.
