| 1 | In-situ microstructural investigations of the TRIP-to-TWIP evolution in Ti-Mo-Zr alloys as a function of Zr concentration显示文摘Aiming at overcoming the strength-ductility trade-off in structural Ti-alloys,a new family of TRIP/TWIP Ti-alloys was developed in the past decade(TWIP:twinning-induced plasticity;TRIP:transformationinduced plasticity).Herein,we study the tunable nature of deformation mechanisms with various TWIP and TRIP contributions by fine adjustment of the Zr content on ternary Ti-12 Mo-xZr(x=3,6,10)alloys.The microstructure and deformation mechanisms of the Ti-Mo-Zr alloys are explored by using in-situ electron backscatter diffraction(EBSD)and transmission electron microscopy(TEM).The results show that a transition of the dominant deformation mode occurred,going from TRIP to TWIP major mechanism with increasing Zr content.In the Ti-12 Mo-3 Zr alloy,the stress-induced martensitic transformation(SIM)is the major deformation mode which accommodates the plastic flow.Regarding the Ti-12 Mo-6 Zr alloy,the combined deformation twinning(DT)and SIM modes both contribute to the overall plasticity with enhanced strain-hardening rate and subsequent large uniform ductility.Further increase of the Zr content in Ti-12 Mo-10 Zr alloy leads to an improved yield stress involving single DT mode as a dominant deformation mechanism throughout the plastic regime.In the present work,a set of comprehensive in-situ and ex-situ microstructural investigations clarify the evolution of deformation microstructures during tensile loading and unloading processes. | Bingnan Qian Jinyong Zhang Yangyang Fu Fan Sun Yuan Wu Jun Cheng Philippe Vermaut Frederic Prima | 2021 | Journal of Materials Science & Technology2021，，6： | 2 |
| 2 | A kink-bands reinforced titanium alloy showing 1.3 GPa compressive yield strength:Towards extra high-strength/strain-transformable Ti alloys显示文摘1.Introduction In structural metallic materials,the occurrence of particular deformation mechanisms such as dislocation slip,deformation twins(DTs)[1,2]deformation kink bands(KBs)[3,4]or stressinduced phase transformations(SIM)[5],are closely related to both their crystal structures[6–8](e.g.FCC,BCC and HCP)and loading conditions(e.g.temperature and/or strain rate). | Jinyong Zhang Bingnan Qian Yijin Wu Yu Wang Jun Cheng Zheng Chen Jinshan Li Fan Sun Frederic Prima | 2021 | Journal of Materials Science & Technology2021，，15： | 1 |
