The residual stress, equiaxed crystal grain size and surface roughness of laser cladding deposition TC4 samples after micro forging treatment are tested, and room-temperature tensile properties and anisotropy of samples in deposition state, solution state and micro forging-solution aging state are analyzed. The results show that the columnar crystal grains transform into equiaxed grain with size variation from 70 μm to 140 μm after micro forging treatment. After micro forging treatment, the plasticity of the formed parts in horizontal direction is significantly improved, the tensile properties in all directions are higher than those of the forging parts, and the anisotropy of the formed parts is less than 10%.
