| Popis: | Iron aluminide (Fe3Al) composites reinforced with ~3 wt% of carbon nanotube (CNT) were fabricated by hot press consolidation. Ambient-temperature mechanical properties of the iron aluminide—CNT composites were determined. The hardness, compressive yield strength, and bending strength hardness of composites were higher by 63%, 1%, and 5%, respectively. Microscopic examination of the composite showed the added CNTs still keep their tubular structure. The preliminary results on the processing and improvement in mechanical properties of CNT-reinforced iron aluminide matrix composites are being reported here for the first time. |
