“…26 Similar to the values of Uenishi et al, these are larger than those measured for vapor-quenched 4,5 and liquid-quenched samples. 46 It is likely that the difference between the values for HEBM samples and those processed using liquid-and vapor-quenching techniques is due to the total strain energy in the lattice introduced by the processing technique.…”

Extended x-ray-absorption fine-structure ͑EXAFS͒ measurements were used to obtain element-specific, structural, and chemical information of the local environments around Cu and Fe atoms in high-energy ballmilled Cu x Fe 1Ϫx samples ͑xϭ0.50 and 0.70͒. Analysis of the EXAFS data shows both Fe and Cu atoms reside in face-centered-cubic sites where the first coordination sphere consists of a mixture of Fe and Cu atoms in a ratio which reflects the as-prepared stoichiometry. The measured bond distances indicate a dilation in the bonds between unlike neighbors which accounts for the lattice expansion measured by x-ray diffraction. These results indicate that metastable alloys having a positive heat of mixing can be prepared via the high-energy ballmilling process. ͓S0163-1829͑96͒10033-3͔

“…In 1960, Duwez et al created successfully amorphous material. [3] In 1976, Takayama fabricated amazingly Ag x Cu 1-x ; x = 0.35 ÷ 0.65 alloy in amorphous state [4]. In 1999, Qi et al [35] produced excellently CuNi material in amorphous and liquid states by using fast-cooling method [23][24][25][26].…”

This paper studies the influence of atomic number at temperature of 300 K, temperature at 5324 atoms, phase transition & crystallization at different temperatures of 300 K, 500 K, 600 K, 700 K, 1100 K after 2×10 5 move steps number by increasing temperature of 4×10 12 K/s on microstructure, phase transition temperature, phase transition & crystallization of CuNi nanoparticle by molecular dynamics (MD) with embedded interaction Sutton-Chen and soft boundary conditions. Microstructure characteristics are analyzed through radial distribution function (RDF), energy, size, phase transition temperature (via relationship between energy and temperature), phase transition & crystallization (via radial distribution function, E tot , move step number and common neighbor analysis (CNA)). Results show that first peak position of the radial distribution function is dominant; lengths of Cu-Cu, Ni-Ni with the results of Ni-Ni consistent with simulation. At 300 K temperature, nanoparticle appears in four phases namely FCC, HCP, ICO and Amorphous, presenting the effect of atomic number, temperature and move step number on microstructure, phase transition temperature and phase transition & crystallization of CuNi nanoparticle.
