"caption": "Panel a displays engineering stress-strain curves comparing a \"CNL alloy\" (red line), a \"Severely deformed alloy\" (blue line), and a \"Conventionally processed alloy\" (black line), where the y-axis represents \"Engineering stress (MPa)\" up to 2000 and the x-axis represents \"Engineering strain (%)\" up to 20. Panel b presents microstructural analysis, starting with a high-resolution TEM image with a 1 nm scale bar that distinguishes between \"FCC\" and \"L1₂\" phases using FFT patterns labeled \"Z=[001]\". Below the TEM image are elemental distribution maps for Fe, Co, Cr, Ni, Al, and Ti, alongside an \"All\" composite map, which use a 50 nm scale bar and arrows to indicate the spatial correlation with the \"FCC\" and \"L1₂\" phases.",

The graph plots Engineering stress in MPa versus Engineering strain in percent for a \"Base alloy,\" \"Al8Ti6,\" and \"Al7Ti7,\" showing the Al7Ti7 sample achieving the highest strength over 1400 MPa and elongation past 50%. The lower section displays three microscopy images taken at 10%, 20%, and 38% strain, with specific features labeled \"HDDWs\" and \"MBs\" visible in the latter two images alongside scale bars of 0.5 μm and 2 μm. A color-gradient arrow at the bottom points right with the text \"Increased plastic deformation,\" linking the microstructural changes to the increasing strain levels.",
