Local Structural Features of Metallic Alloys: Ni_{33}Zr_{67} and Ni_{50}Zr_{50}

Development of Metallic Sensory Alloys

Existing nondestructive evaluation (NDE) technologies are inherently limited by the physical response of the structural material being inspected and are therefore not generally effective at the identification of small discontinuities, making the detection of incipient damage extremely difficult. One innovative solution to this problem is to enhance or complement the NDE signature of structural ...

Strain relaxation mechanisms and local structural changes in Si1ÀxGex alloys

In this work, we address issues pertinent to the understanding of the structural and electronic properties of Si12xGex alloys, namely, ~i! how does the lattice constant mismatch between bulk Si and bulk Ge manifest itself in the alloy system? and ~ii! what are the relevant strain release mechanisms? To provide answers to these questions, we have carried out an in-depth study of the changes in t...

Local Charge Distributions in Metallic Alloys: a Local Field Coherent Potential Approximation Theory

Metadislocations in Complex Metallic Alloys

Complex Metallic Alloys (CMAs) represent a large group of crystalline intermetallics comprising some hundreds of known phases in various alloy systems. They are characterized by the presence of icosahedral atom coordination, large lattice constants, and a correspondingly large number of atoms per unit cell, typically ranging between a few tens and some thousand [1]. In recent years, CMAs have a...
