Based on the results of experiments performed at temperatures T ≳ 613 K, a thermodynamic model was recently proposed to explain: (i) the origin of a metastable liquid miscibility gap (MLMG) in Pd-Ni-P, an alloy system with a negative heat of mixing

Recently, for the first time, a metastable liquid miscibility (MLMG) in a metallic alloy system was found and determined (Z. D. Wu et al. J. Non-Cryst. Solids 410 (2015) 51–57 and W. Z. Zhou et al., J. Non-Cryst. Solids, 432 (2016) 420–425). Acco

Polyamorphic transition is the transition between two amorphous states or two liquid states (LLT) at a fixed composition of a substance. Experience in LLT is limited. Besides, its nature remains largely unknown as it occurs under the experimental con

Despite having a negative heat of mixing, a metastable liquid/amorphous miscibility gap (MLMG) was found below the liquidus of the alloy system, Pd–Ni–P. Earlier, a direct determination of the complete MLMG was not possible because it lies in the

Recently, it was found that undercooled molten Pd–Ni–P undergoes amorphous/liquid spinodal decomposition or equivalently the alloy system has a metastable liquid miscibility gap (MLMG) in its undercooling regime. This is unusual because the alloy

Pd41.25Ni41.25P17.5 bulk metallic glasses (BMGs) undergo phase separation despite the fact that the alloy system has a negative heat of mixing. By employing the techniques of small angle X-ray scattering (SAXS), it was found that the phase separation

Phase-separated Pd41.25Ni41.25P17.5 bulk metallic glasses (BMGs) were subjected to isothermal annealing at 613 K (340 °C) for different time periods, t, in the range of 0 ≤ t ≤ 8 hours. For 0 ≤ t ≲ 5 hours, crystalline precipitates, in the s

Earlier, it was shown that molten Pd 41.25 Ni 41.25 P 17.5 alloys can be cast into BMGs (bulk metallic glasses) of different microstructures, which are: (i) homogeneous BMGs (A-type), (ii) homogeneous BMGs embedded with crystalline precipitates (B-ty

Molten Fe79.5B6.5C14 melts can be cast into ingots of networklike microstructure. According to microstructural classification, a Fe79.5B6.5C14 network specimen can be divided into three zones. Zone A is occupied by a random network, zone B by a unifo

Experimental arrangements were made to study the spinodal mechanism occurring in undercooled molten Pd 41.75 Ni 41.75 P 17.5 alloys as a function of time. It can be estimated from the experimental results that the lower bound of the duration (or comp
