Abstract
Ni based amorphous alloys with Si and B, which can also, contains Fe and Cr, prepared by rapid solidification, have low melting temperatures. This fact increases their susceptibility to be joined by welding and brazing.
The glass forming ability (GFA) is conditioned also by the crystallization delay, due to certain chemical composition of the alloys.
The thermal stability of these alloys was revealed by DTA analysis and structural characteristics were investigated by XRD.
Applying an annealing at temperatures between 420°C and 540°C, with 30 minutes maintaining time, allowed the investigation of phase occurred during the crystallization and the estimation of the crystalline grains dimensions.
