During solidification, in-situ formed NbB2 phase in liquid Al contributed for enhanced heterogeneous nucleation, which caused a dramatic refinement of primary Al grain size, uniformly distributed second phases and enhanced wear characteristics.eninfo:eu-repo/semantics/openAccessAl-NbB2 in-situ compositesMicrostructureGrain refinementWearArticle10.1016/j.matlet.2022.1333772-s2.0-85140800515Q2330WOS:000879519900001Q2
