EFFECT OF THE ROLLING MODE ON TEXTURE DEVELOPMENT OF 26CU-2FE-72NI ALLOY SYSTEM

The main objective of the present work was to study the cold rolled texture of 26cu-2fe-72ni alloy system at different reductions using the xrd analysis techniques and then co-relate it with various mechanical properties. the 26cu-2fe-72ni alloy was produced from pure elemental constituents using a vacuum induction melting furnace and casted as cylindrical ingots having 10 cm length and 5 cm diameter. for homogenization of the structure the cast ingots were heated to 950 ºc for six hours and cooled in the furnace. then, these ingots were hot forged using an open die forging to form samples having dimensions 200 x 45 x 10 mm approximately. the forged plates were cut into two halves and each one was cold rolled (unidirectionally) to a final thickness of 0.69 mm. during rolling after every 25 % reduction, the cold rolled samples were annealed at a temperature of 900 ºc for one hour. the diffraction patterns were scanned using siemens jeol jdx-99c x-ray diffractometer with ni-filter and cu-k radiation for xrd analysis of cast and rolled samples. the deformation texture was then co-related with the mechanical properties, e.g. hardness, uts, yield strength and elongation. it was observed that the intensity of (111) plane gradually decreases where as intensity of (220) plane gradually increases after cold rolling.
