Investigation of Physical-Mechanical Properties and Structure of Layered Cermet Al–Al2O3–Al4C3

  • Published:
Refractories and Industrial Ceramics Aims and scope

The layered cermet Al–Al2O3–Al4C3 was obtained by liquid-phase sintering under vacuum of powder blanks made of highly disperse PAP-2 industrial brand Al powder consisting of flaky particles of submicron thickness. The appearance of the liquid phase was associated with the formation of an Al/Al4C3 eutectic melt at 630°C as a result of the reaction of Al with its carbide. Lamellar nanoscale Al4C3 crystals separated upon cooling of the eutectic melt and acted as a disperse hardener in the Al matrix. An aluminum-oxide phase (δ-Al2O3) formed, increased the hardness of the cermet, and resulted from the reaction of Al with residual atmospheric oxygen during sintering at a pressure of 10–5 mm Hg in the furnace. The main properties of the obtained cermet were density 2.56 – 2.65 g/cm3, bending strength 300 – 500 MPa, and crack resistance 9 – 15 MPa·m1/2. A material of composition Al 80%, Al4C3 14%, and δ-Al2O3 6% retained a high bending strength (200 MPa) at 500°C.
