To ensure uniform composition, each sample underwent four re-melting and re... | 7, 8, 10 | Raw elemental material, Al, Co, Cr, Fe, and Ni with purity higher than 99.5wt% and master alloy, Fe-61.5wt% Mo, all in granular shape were melted to prepare the alloys by using arc-melting method under a protective atmosphere of argon [8]. Four times of re-melting and re-solidification were performed for each sample to... | null | true |

It exhibited a room temperature Vickers hardness of Hv 770. While it had similar hardness to Co-0.5, its crack length was significantly shorter (about 13mm vs. 91mm for Co-0.5), indicating superior fracture toughness, which is attributed to its fine modulated microstructure... | 1, 27, 28, 30, 33, 35, 36, 37, 44 | All the AlCoxCrFeMo0.5Ni alloys possess higher hardness level than that of Ni-based super-alloys In 718/In 718H from room temperature to 1273K [1]. Both alloys of x¼ 0.5 and 1.0 exhibit a transition temperature higher than that of Co-based alloy T-800 by about 200K [1]. They also have a high hot hardness of Hv 347 at 1... | null | true |
