| Zusammenfassung: | This work was aimed to produce ... powder through two-step reactions and to sinter it under a pressureless condition, and the related synthesis and sintering mechanisms were evaluated. ... powder of ...9 ...m in size was produced using ... and Al powders and sintered to a relative density of ...95.5%. The sintering was characterized by an activation energy of 267±23 kJ/mol and the mixed mode of sintering comprised of the surface diffusion mechanism and the transient liquid-phase sintering caused by melting of Al-Cr intermetallic impurities. The sintered sample exhibited Vickers hardness of 3.4 GPa. (ProQuest: ... denotes formulae/symbols omitted.) |
