Interfacial properties of immiscible Co–Cu alloys

Formation of ordered and disordered interfacial films in immiscible metal alloys

Article history: Received 9 August 2016 Received in revised form 8 November 2016 Accepted 20 November 2016 Available online xxxx Atomistic simulations are used to study segregation-induced intergranular film formation in Cu\\Zr and Cu\\Nb alloys. While Cu\\Zr forms structurally disordered or amorphous films, ordered films comprised of a second phase usually precipitate in Cu\\Nb, with a critica...

Se p 19 99 Magnetic properties of disordered CoCu alloys : A first principles approach

CoCu alloys have been extensively studied experimentally. Earlier investigations, particularly those of the magnetic properties, include high-temperature magnetic moment for 4085% Cu rich Co-Cu solid solutions [1] and variation of magnetic moments for Co rich alloys at room temperature [2,3]. Recently, the focus of attention has been on giant magneto-resistance (GMR) studies. Several experiment...

Interfacial stability of immiscible displacement in a porous medium.

Synthesis, Mechanical and Tribological Characteristics of Immiscible Alloys

A modified impeller mixing coupled with chill casting technique was used for the preparation of immiscible alloys. In this paper Al-Fe binary alloys was chosen for this study. This binary system shows the miscibility gap at specified concentration and temperature. The electrolytic grade iron powder of 300mesh size was dispersed in the melt of commercially pure aluminum. The iron content in the ...

An Atomistic Study of Interfacial Diffusion in Lamellar TiAl Alloys

In this paper we investigate self-diffusion of Ti and Al along interfaces present in the lamellar L10 TiAl by atomistic computer modeling. The interactions between the atoms are described by centralforce many-body potentials. The approach adopted is similar to that used in earlier atomistic modeling of bulk diffusion in TiAl [1, 2]. Both the formation and migration of vacancies is examined. The...
