| Abstract Scope |
Titanium alloys incorporating twinning induced plasticity(TWIP) and transformation induced plasticity(TRIP) have been a subject of research taking inspiration from steel where they give exceptional work hardenability. Classic titanium alloys, have excellent mechanical properties but lack the work hardenability that can be offered by TWIP and/or TRIP. Currently, most TWIP and TRIP titanium alloys have lower yield stresses than traditional Ti alloys. In this work, a new TWIP/TRIP titanium alloy was developed to increase the yield strength and work hardenability of the alloy through a combination of interstitial/substitutional solid solution strengthening and precipitation strengthening. Novel heat treatments were performed to optimize the size and volume fraction of the a phase as well as the mechanical properties. Tensile properties of selected samples were determined. Detailed characterization of the deformed microstructures was performed using a combination of SEM and TEM techniques. These results will be presented and discussed. |
