Microhardness value increased by 45% after 4 ECAP passes. With further increase in ECAP passes, samples attained a saturated state. Similar trend was observed in Ultimate tensile strength with an increase of 54% as compared to homogenized sample and reached a maximum value of 562 MPa. Increase in mechanical property was attributed to strengthening by grain refinement and dislocation strengthening. XRD analysis showed the absence of precipitate in the deformed specimens. © 2022, The Institution of Engineers (India).Grain refinementGrain size and shapeNickel alloysTensile strengthC70600Copper nickel alloysCu -Ni alloysGrains refinementMechanical characterizationsMetallurgical behaviorMicro-structuralPressing passSaturated stateSPDEqual channel angular pressing
