Experimental and theoretical results obtained in the MULTIPHAS-project are discussed regarding solidification kinetics of glass forming Zr50Cu50 and Zr50Cu30Ni20 alloy samples. The samples are investigated during solidification using a containerless technique. Applying elaborated methodologies for ground-based and microgravity experiments, the kinetics of dendritic solidification is quantitatively evaluated. The solidification kinetics is determined using a high-speed camera [1]. Experimental results on solidification kinetics are interpreted using theory of dendritic growth together with the analysis of the cluster structure behavior in glass-forming melts with the increase of undercooling [2].
