A Ti40Zr40Ni20 quasicrystal (QCs) rod and ribbons were prepared by conventional casting rapid solidification. The X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission (TEM) differential calorimeter (DSC) techniques used to investigate the microtissue, phase composition, solidification features of samples; nano-indentation test was carried out at room temperature. results...

The high undercooling of binary Co-4.54%Sn alloy has a significant influence on its microstructural characteristics and physical properties. Here, we report that the dendritic growth properties broad-temperature-range remarkably depends during rapid solidification. maximum attains 208 K at molten state, velocity is quite sluggish in highly undercooled liquid because it broad solidification rang...
