Tension–compression asymmetry of 〈c+a〉 slip in Ti–6Al

Abstract:

Microcantilevers with triangular cross-sections were machined using a focused ion beam from an α Ti–6Al alloy. Plasticity was predominantly in the lower part of the cantilever, allowing tension–compression asymmetry to be investigated by bending the cantilever up or down. Both ⟨a⟩ prismatic slip and pyramidal slip were investigated. The critical resolved shear stress was determined by calibrating a crystal plasticity model and found to be 329 MPa for ⟨a⟩ prismatic slip in both tension and co...
