摘要: Four sizes (1, 2, 5 and 10 µm wide) of single-crystal α-Ti micro-cantilevers were manufactured from polycrystalline commercially pure Ti samples using a focussed ion beam. A nanoindenter was used to conduct micro-bending tests. The crystal orientation alignment the micro-cantilever beams selected so as activate only ⟨a⟩ slip on prism planes. plasticity finite element model simulate deflection behaviour cantilevers. critical resolved shear stresses (CRSS) determined via reverse process fitting simulation results experimental load–displacement curves. CRSS increased 144 MPa for wide cantilevers 566 1
