Abstract
The purpose of this paper is to examine the microstructural evolution and mechanical properties of Ni/Ti laminated composite produced by a cross-accumulative roll bonding (CARB) method. The SEM images showed that no void and delamination were observed which indicates that the layers were strongly bonded together. In addition to the thickness reduction and increased number of interfaces, plastic instabilities took place with an increase in CARB passes; the wavy-like interfaces appeared as a result of the necking and shear bands formation. However, due to the effect of uniform rolling pressure and rotation of rolling direction during the CARB process, all layers remained continuous in all CARB passes. The most marked observation coming from EBSD analyses was the formation of fine grains surrounded by a high fraction of high-angle grain boundaries (HAGBs). Based on the microtexture analyses on Ti and Ni layers, it was found that by increasing the rolling passes, a crystallographic texture formed in Ti layers gradually changes from the basic {0001}[removed] system into the system dominated by {0001}[removed] prismatic-like orientations. In the case of the crystallographic texture formed in Ni layers, there was a significant increase in the intensity of the Q{013}[removed]; P{011}[removed] and Goss {011}[removed], indicating the formation of shear strain-assisted type of texture. Furthermore, with an increase in the CARB passes, the mechanical properties improved due to strong interfaces and grain refinement. The maximum values of the yield strength, tensile strength, and elongation reached 842 MPa, 936 MPa, and 7.1% respectively, in the final CARB pass. In addition, ductile fracture mainly occurred on fracture surfaces of Ti and Ni layers even though by increasing passes, cleavage facets appeared due to strain hardening.
