Abstract Effect of surface treatment on tensile property of a near lamellar gamma-based TiAl-alloy Ti-45Al-5Nb-1W-1B (atom fraction, %) has been investigated. The results show that the highest tensile strength of the alloy at room temperature and high temperature can be achieved by shot peening. The alloy processed by turning possesses a tensile strength close to that of shot penned one at room temperature, however a dramatic decline at high temperature. Electro polishing leads to the lowest tensile strength at room temperature, but a tensile strength at high temperature as high as that of shot penned one. Although the residual compressive stress can be introduced by shot peening and turning, besides a surface layer of deformation can also be caused by the former, therefore the compressive residual stress induced by shot penning is higher than that by turning. Meanwhile, crack initiation has been transferred from surface to subsurface because of the existence of the residual compressive stress.
