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 compression. However significant tension–compression asymmetry was observed for pyramidal slip; increasing to 820 MPa under compression and decreasing to 558 MPa in tension.
