Microstructural evolution of slowly solidified Cu-Ti-Zr-Ni amorphous alloy

Microstructural characterization of rapidly solidified Cu 50 Zr 40 Ni 5 Ti 5 amorphous alloy

“…Many studies have been carried out on mechanical properties and microstructural characterization of Cu-Ti and Cu-Zr [10,11] binary alloys, Cu-Mg-Ni, Cu-Zr-Al [12,13], Cu-Zr-Ti [14], Cu-Zr-Ni, Cu-Zr-Ag [15,16] ternary alloys, Cu-Ti-Zr-Ni [17], quaternary alloys and also Cu-Ti-Zr-Ni-Be [18,19], Cu-Ti-Zr-Ni-Si [20,21] quinary alloys which manufactured by different techniques. Hence, the properties of Cu-based alloys have been improved continuously.…”

Spherulitic growth process in Ti-based metallic glass: Microstructure, phase identification, and growth mechanism

“…Only phases containing the two major elements of the grade, i.e., Cu and Ti, were considered as possible solutions. This rather simple assumption is first based on previous literature results [15,16] and second coherent with the fact that Zr and Pd have electronic structures and atomic radii that allow them to substitute for Ti and Cu, respectively [12]. All the results (XRD patterns, EBSD maps, and EDS, SAED-TEM, and ASTAR TEM analyses) were consistent with this hypothesis, and it was observed that the major phases present have similar structures as Cu 3 Ti 2 , CuTi (tetragonal and B2 cubic), and CuTi 3 .…”

“…Phase identification for a non-equilibrium state with four different components is a difficult task. To identify possible candidates for the different phases observed, a strong hypothesis was made, which is that the minor elements (Zr and Pd) would substitute for the major elements (Cu and Ti) [15]. This rather strong assumption was necessary to identify possible candidates from the Cu-Ti system among all possible structures in the literature.…”

“…This rather strong assumption was necessary to identify possible candidates from the Cu-Ti system among all possible structures in the literature. It is worth noting that this assumption is quite classical and can be found in the literature on alloys with a composition close to the one studied here [15][16][17] Phase identification was performed using the phases presented in Table 1.…”

Structure and Mechanical Behaviour of Cu‐Zr‐Ni‐Al Amorphous Alloys Produced by Rapid Solidification

“…In the rapid solidification method, the amorphous alloys are manufactured on thin ribbons forms, which are usually ductile and bright surface. Many Cu-based binary, ternary, quaternary and quinary alloys have been manufactured by these methods [9][10][11][12][13][14][15]. In this work, Cu-Zr-Ni-Al quaternary amorphous alloys are produced by rapid solidification technique at wheel surface velocities of 35 and 41 ms -1 as ribbons forms with very flexible.…”
