“…A strong interfacial bond between the ceramic particle and aluminium matrix is advantageous in terms of toughness [25,26]. The fracture toughness of Al 2 O 3 P/steel composites was investigated by Schlenther et al [27] and it was noticed that the cracking sources were influenced by increasing the brittle ceramic materials. Similar results were found by Alaneme and Aluko [28] where fracture toughness of SiC reinforced Al 6063 composites was evaluated and in result fracture toughness enhanced attributable to increase volume percentage of SiC reinforcement.…”

During the service life of components, they encounter several cyclic loadings that consequently generate stress which encourages crack interaction ultimately deteriorating materials’ performance. The present study aims to investigate the fracture behaviour of aluminium 6061 reinforced with 0-15 wt.% ZrO2 particles (at step of 5 wt.%) fabricated using stir casting technique. Compositional analysis through X-ray diffraction was performed on the prepared composite samples. The fracture toughness of prepared composites is investigated through bending test by using single edge notch bend (SENB) specimens. In addition, the computation of fracture toughness was also performed by finite element analysis (FEA) approach, and the numerical results obtained from the FEA were compared with the experimental value. Furthermore, fractography and microstructural tests were carried out in order to investigate the influence of reinforcement weight percentage on the failure behaviour of the composites that had been prepared. The results show that with inclusion of ZrO2 (15 wt.%) in aluminum 6061 matrix the maximum fracture toughness of 500.83 MPa.mm0.5 was observed. The study performed through FEA highlights the stress phenomena and result are in good agreement with the experimental results.

“…In recent years, macrostructured composites have received a lot of attention because of their good fatigue resistance and fracture resistance, which is expected to further improve the mechanical properties of composites [5][6][7][8]. Zhipeng Liu et al [9] studied the properties of the macrostructured composites at what pore size/pore wall ratio of the preform, and the results showed that the composite exhibited good compressive and wear resistance at this ratio when the pore size/pore wall ratio was 1.25.…”

Zirconia toughened alumina particles (ZTAp)/high chromium cast iron (HCCI) matrix honeycomb composites were successfully prepared by a non-pressure infiltration casting process. This paper systematically investigates the effect of pore size (6mm, 8mm, 10mm, 12mm) on the compression resistance of honeycomb structure under the same wall thickness condition. Through the simulation software Ansys Workbench and compression performance test, it was found that the fracture location of the composite material occurred mainly at the interface location between the composite area and the matrix area during the compression process of the specimen, and the actual compression results were consistent with the simulation results. The compression performance tends to increase gradually with the increase of the honeycomb pore size, and the optimal compression resistance is reached when the pore size is 12 mm. This optimum performance is attributed to the fact that the reinforcement mechanism of the composite depends not only on the load sharing of the reinforcing particles, but also on the strength of the matrix.

“…Over the recent decades, ceramic particulates reinforced metal matrix composites have attracted much attention owing to their superior wear resistance. In particular, Al 2 O 3 particulates (Al 2 O 3 p)-reinforced iron or steel matrix (Al 2 O 3 p/iron(steel)) composites have become the hot point of research and applications owing to their superior wear resistance and low costs [1][2][3][4][5][6]. However, the low ductility and toughness of Al 2 O 3 p/steel composites are the fatal weakness for their wider 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.
