Embodiment 1
[0036] Alloy 4D prints NiTi alloy, and prepares EBSD samples according to the following steps.
[0037] (1) Cutting: The 4D printed NiTi alloy samples were cut by wire cutting method. In this embodiment, the 4D printed NiTi alloy to be cut is fixed on a wire cutting machine, and cut along the section to be analyzed, and the thickness of the 4D printed NiTi alloy sample is 1 mm.
[0038] (2) Cleaning: Use acetone solution to clean the cut samples to remove metal powder and oil stains remaining on the surface during the cutting process.
[0039] (3) Inlay: use CMR2 to inlay the cut sample, and the thickness after inlay is 12mm.
[0040] (4) Grinding: Use 400#, 1200# diamond grinding discs and 2000#, 3000#, 5000# silicon carbide sandpaper to grind the surface of the 4D printed NiTi alloy sample under water cooling until no scratches are observed with the naked eye. In this embodiment, a grinding and polishing machine is used to grind the sample, and water is continuously added ...
