Compressive performance and crack propagation in Al alloy/Ti2AlC composites

  title={Compressive performance and crack propagation in Al alloy/Ti2AlC composites},
  author={D.A.H.Hanaor and L.Hu and W.H.Kan and G.Proust and M.Foley and I.Karaman and M.Radovic},
Composite materials comprising a porous Ti2AlC matrix and Al 6061 alloy were fabricated by a current-activated pressure assisted melt infiltration process. Coarse, medium and fine meso-structures were prepared with Al alloy filled pores of differing sizes. Materials were subjected to uniaxial compressive loading up to stresses of 668 MPa, leading to the failure of specimens through crack propagation in both phases. As-fabricated and post-failure specimens were analysed by X-ray microscopy and…
