Title

Plastic Strain Accommodation and Acoustic Emission During Melting of Embedded Particles

Abstract

Melting point phenomena of micron-sized indium particles embedded in an aluminum matrix were studied by means of acoustic emission and differential scanning calorimetry. The acoustic response measured during melting increased with indium content. Correlations with differential scanning calorimetry suggest that large indium particles or particles at grain boundaries generate the greatest acoustic emission. Acoustic emission during melting suggests a dislocation generation mechanism to accommodate the 2.5% volume strain required for melting of the embedded particles. © 2012 Elsevier B.V.
