Abstract
Disclosed are a 4D printing method and application of titanium-nickel shape memory alloy. The 4D printing method comprises the following steps: mixing and smelting pure titanium and pure nickel to obtain titanium-nickel alloy bars, then preparing alloy powder by a rotating electrode atomization method, and sieving the powder to obtain titanium-nickel alloy powder with a particle size of 15-53 μm; placing the obtained titanium-nickel alloy powder in a discharge plasma assisted ball mill for discharge treatment to perform surface modification of the powder; and subjecting the titanium-nickel alloy powder to SLM forming to obtain the titanium-nickel shape memory alloy.
