Microstructural refinement of Ti-44Al-11Nb by severe plastic deformation

Journal Article · · Scripta Materialia

Recent studies have demonstrated that Seere Plastic Deformation (SPD) can be successfully used to produce submicrometer sized grains. Equal Channel Angular Extrusion (ECAE) has proven to be an effective technique for producing severe plastic deformation. With the objective of producing sub micron grains and determining the beneficial effects of such microstructures on mechanical properties, the authors have an ongoing study of severe plastic deformation effects in several TiAl and Ti{sub 3}Al based intermetallics. The microstructural modifications in a Ti-44Al-11Nb (all compositions are in atomic percent) alloy processed by equal channel angular extrusion are evaluated.
