Notes:
Al-Ti alloys, which have Al3Ti platelet particles in Al matrix, were deformed by ECAPwith routes A and Bc. With increasing the number of ECAP passes, Al3Ti platelet particles arefragmented and their sizes decrease. The microstructure of ECAPed Al-Ti alloy specimens by routeA has a strong alignment of the fragmented Al3Ti particles. On the other hand, ECAPed Al-Ti alloyspecimens by route Bc have a relatively homogeneous distribution of Al3Ti particles comparing withthe specimen deformed by route A. Based on these results, it was found that ECAPed Al-Ti alloyspecimen by route A has highly anisotropic microstructure. However, both ECAPed specimens withroutes A and Bc have no anisotropic wear property. That is because the wear property of the Al-Tialloy specimen depends on the shape of the Al3Ti particle. From these results, it was found that SPDinduced by ECAP is an effective processing method to make homogeneous wear property for themetallic material containing platelet solid-particles
