Fecha de publicación: | 2014 | Editor: | Elsevier | Citación: | Materials Science and Engineering: A 590 :140 - 146 (2014) | Resumen: | The temperature dependence of the stress-induced martensite (SIM) formation in a Ti-10V-2Fe- 3Al (Ti-1023) alloy under compressive loading has been studied. At low temperatures, the stress level at which martensite starts to form increases linearly with the deformation temperature, while the stress at which the deformation switches to regular plastic deformation is roughly temperature independent. A thermostatistical model for dislocation evolution is employed to describe deformation twinning in martensite. Combined effects of twinning induced plasticity and solid solution strengthening are considered in terms of temperature variations. The SIM effect disappears on deformation at temperatures beyond s233 C, which is close to the predicted Ms temperature of 240 C. The thermostatistical model predicts a transition from twinned martensite to pure slip at 250 C. By providing a model to predict stress induced martensite formation, and by describing deformation twinning, the present work provides a number of tools that may be employed to conceive new titanium alloys combining improved strength and ductility | URI: | http://hdl.handle.net/10261/88909 | DOI: | 10.1016/j.msea.2013.10.003 | ISSN: | 0921-5093 |
