Spatial distribution of spherical Al3Ti particles in Al-Al3Ti composite by equal-channel angular pressing (ECAP) and multi-directional forging (MDF) are investigated. The Al-Al3Ti composite containing spherical Al3Ti particles in the Al matrix is fabricated by spark plasma sintering (SPS). The spherical Al3Ti particles in the Al-Al3Ti composite are not fragmented by both ECAP and MDF. This is because that stress concentration induced around the spherical Al3Ti particles is relatively small. Furthermore, spatial distribution of the spherical Al3Ti particles in the deformed Al-Al3Ti composite is evaluated by Morisita index analysis. As a result, it is found that spatial-distribution change of the spherical Al3Ti particles in the Al-Al3Ti composite by both ECAP and MDF depends on the particle size. This phenomenon can be also explained by the stress concentration around the spherical Al3Ti particles.
