0 ” Cold Melting ” of Invar Alloys
An anomalously strong volume magnetostriction in Invars may lead to a situation when at low temperatures the dislocation free energy becomes negative and a multiple generation of dislocations becomes possible. This generation induces a first order phase transition from the FCC crystalline to an amorphous state, and may be called " cold melting ". The possibility of the cold melting in Invars is...
متن کاملFerromagnetic Ga1ÀxMnxAs produced by ion implantation and pulsed-laser melting
We demonstrate the formation of ferromagnetic Ga12xMnxAs films by Mn ion implantation into GaAs followed by pulsed-laser melting. Irradiation with a single excimer laser pulse results in the epitaxial regrowth of the implanted layer with Mn substitutional fraction up to 80% and effective Curie temperature up to 29 K for samples with a maximum Mn concentration of x'0.03. A remanent magnetization...
متن کاملHIGH-STRENGTH NANOCRYSTALLINE Ni-W ALLOYS PRODUCED BY ELECTRODEPOSITION
Nanocrystalline Ni-W alloys having both high ductility and high strength were produced by electrodeoisition. The plating bath for the electrodeposition contained nickel sulfate, citric acid, sodium tungstate and ammonium chloride, and was operated at various bath concentrations and conditions of electrolysis. The ductility and tensile strength of the deposited alloys are strongly influenced by ...
متن کاملEntropy behavior in cluster melting.
We analyze the configurational excitation of a cluster for both a microcanonical and a canonical ensemble of atoms and apply this analysis to the Lennard-Jones cluster of 13 atoms. Dividing the cluster excitations into configurational and thermal classes, we evaluate the anharmonicity coefficient of atomic vibrations and the entropy jump as a function of temperature on the basis of computer sim...
متن کاملImpurity effects on the melting of Ni clusters
We demonstrate that the addition of a single carbon impurity leads to significant changes in the thermodynamic properties of Ni clusters consisting of more than a hundred atoms. The magnitude of the change induced is dependent upon the parameters of the Ni–C interaction. Hence, thermodynamic properties of Ni clusters can be effectively tuned by the addition of an impurity of a particular type. ...
