Body-centred cubic (BCC) Ti–18Zr–13Mo (wt%) alloy displays excellent yield strength (≈800 MPa), stable hardening (rate > 1500 MPa) and uniform ductility >18%, resulting from multi-TWIP (multiple twinning-induced plasticity) strengthening effect. This multimodal mechanisms include micro-scale {332}<113> deformation twinning (DT), nano-scale {112}<111> DT and a rare {5 8 11}<135> DT mode. Martensitic phase transformation is completely suppressed and the sample stays a single-phase solid solution throughout the deformation. In situ electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM) were used to characterize the multi-TWIP and dynamic Hall–Patch effect, with dislocation slip and large grain distortions at twin interfaces.

多重TWIP（多次孪晶）产生的体心立方（BCC）Ti–18Zr–13Mo（wt％）合金具有出色的屈服强度（≈800MPa），稳定的硬化（速率> 1500 MPa）和均匀的延展性> 18％。诱导的可塑性）增强作用。这种多峰机制包括微观尺度{332} <113>变形孪生（DT），纳米尺度{112} <111> DT和罕见的{5 8 11} <135> DT模式。马氏体相变被完全抑制，样品在整个变形过程中保持单相固溶。原位电子背散射衍射（EBSD）和透射电子显微镜（TEM）用来表征多重TWIP和动态霍尔-帕特效应，在双界面处具有位错滑移和大晶粒变形。
