摘要：

MoAlB has been the only known compound with attractive oxidation resistance in the MAB family so far. To widen the application of the MoAlB material in high temperature environments where temperature change is abrupt, the investigation of its thermal shock behavior is required. A dense MoAlB material was prepared by hot pressing of Mo, Al and B elemental powders at 1200 degrees C with 25 MPa for 1 h in Ar atmosphere. Thermal shock resistance of the synthesized MoAlB material was investigated by quenching in water from various temperatures. The residual strength of MoAlB showed a slow decrease trend after quenching from 600 degrees C to 1400 degrees C. The MoAlB material exhibits better thermal shock resistance than another MAB phase of Fe2AlB2. X-ray diffractometry was used to identify the phase composition, and scanning electron microscopy was adopted to characterize the microstructure.
