The glass-forming ability and thermal stability was investigated in a family of Ni-based alloys. The alloys were made by the addition of Al and Ti into Ni 60 Zr 20 Nb 20 . Upon Al addition, the supercooled liquid region ( T x ), the reduced glass transition temperatures (T g /T l ) and γ = T x /(T g + T l ) gradually increase with the increasing Al content. The maximum values of T x = 54 K, T g /T l = 0.615, and γ = 0.405 are reached at the Ni 60 Zr 20 Nb 15 Al 5 composition, which exhibits the largest GFA, a…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
