On the transformation pathways in TRIP/TWIP Ti–12Mo alloy
Résumé
Diverse pathways of the deformation-induced transformations are investigated in the βmetastable Ti-12Mo alloy displaying combined TWIP ({332}<113>β twinning) and TRIP (stress-induced α″) effects by means of Schmid factor analysis and in-situ microstructural characterizations. Two sets of Schmid factors, for {332}<113>β twinning and stress-induced martensite, are calculated in grains of random orientation under uniaxial tension condition. Using in-situ EBSD characterization under tension, the correspondence is mapped between primary transformation products and the grain orientations. The correspondence results graphically in four grain-orientation domains in the inversed pole figure triangle, being twin-dominated, martensite-dominated, combination of both, and the domain unfavorable for both transformations.
