Maney & Son | Citación: | Materials Science and Technology 25 (11) : 1351-1358 (2009) | Resumen: | Investigations into the possibility of improving the strength-ductility relation in a metastable β-titanium alloy (Ti-10V-2Fe-3Al) through plasticity induced transformation (PiTTi) have been carried out. Various heat treatments in the β and/or α+β condition were performed to study their influence on both the microstructure and solute partitioning, which eventually control the PiTTi effect. Stress-induced martensite formation promoting such effect has been observed upon compression testing for β and β+(α+β) microstructures. The stress-strain curves exhibiting stress-induced martensite show ~20% increase in strength, while still retaining a reasonable ductility level. Microstructural parameters such as grain size and solute concentration (especially V) in β have been related to the alloy’s ability to exhibit PiTTi | Versión del editor: | http://dx.doi.org/10.1179/174328408X385773 | URI: | http://hdl.handle.net/10261/73131 | DOI: | 10.1179/174328408X385773 | ISSN: | 0267-0836 |
