Abstract
Copper–Nickel alloy C70600 was processed by equal channel angular pressing (ECAP), at room temperature, up to 8 passes, to study the mechanical properties and metallurgical behavior Microstructural studies showed grain refinement up to fourth ECAP pass. 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).
