“…For example, the ultimate tensile strength and elongation were only approximately 200 MPa and 2%, respectively at Al 2 O 3 volume fraction of 30% where the wear resistance no longer decreased [7]. Kuebler et al [8] found that an enrichment of Ti-activators within the steel matrix as well as the brittle Ti-rich precipitations drastically decreased the toughness of Al 2 O 3 /steel composites. So far, the poor ductility and toughness of Al 2 O 3 p/steel composites is still a key problem for their wide applications.…”

A hierarchical-architectured Al2O3/40Cr steel composite was fabricated by squeeze casting. In the composite, the Al2O3 particulate-reinforced 40Cr steel matrix composite and pure 40Cr steel formed a 3D interpenetrating composite. The uniaxial compressive properties as well as the cracking behaviour, the strengthening and toughening mechanisms of the composite were investigated and discussed. The compressive strength, fracture strain, and elasticity modulus of the architectured composite are 903.5 MPa, 18.8%, and 197 GPa, which are 1.5, 4.0, and 1.7 times the values of the uniformly Al2O3p-reinforced composite, respectively. Special origination and propagation ways of the cracks in the composites were observed with a 3D X-ray microscope, and the contributions of 3D framework structure on the strengthening and toughening of the composite were confirmed.
