Crystallization Behavior of Electrodeposited Pd-Ni-P Metallic Glass Films by Heat Treatment

Abstract

Crystallization behavior of electrodeposited Pd-Ni-P metallic glass films in the supercooled liquid region was investigated. The Pd 40 Ni 40 P 20 , which has the highest glass formability, and other metallic glass Pd 44 Ni 39 P 17 and Pd 41 Ni 42 P 17 were prepared. The crystallization temperature (T x ) of Pd 44 Ni 39 P 17 and Pd 41 Ni 42 P 17 were lower than that of Pd 40 Ni 40 P 20 by differential scanning calorimetry (DSC) analysis. X-ray diffractometry (XRD) patterns show that all samples were crystallized after isothermal annealing below T x . The Pd 5 P 2 and Ni 3 P were observed using XRD analysis after annealing of Pd 40 Ni 40 P 20 and Pd 44 Ni 39 P 17 at 603 K for 60 min and 30 min, respectively. Furthermore, in Pd 44 Ni 39 P 17, the Pd 2 Ni 2 P was observed after annealing at 603 K for 120 min.
