Título: | Evolution of internal strain during plastic deformation in magnesium matrix composites |
Autor: | Garcés, Gerardo CSIC ORCID; Oñorbe, Elvira CSIC ORCID; Pérez Zubiaur, Pablo CSIC ORCID; Denks, I. A.; Adeva, Paloma CSIC ORCID CVN | Fecha de publicación: | 2009 | Editor: | Elsevier | Citación: | Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing 523: 21-26 (2009) | Resumen: | Synchrotron radiation diffraction during in situ tensile tests has been used to evaluate the internal elastic strains within the grains of magnesium alloy, AZ31, unreinforced and reinforced with 5 and 10% volume of SiC particles. Composites present initial thermal residual stresses, which are positive (tensile) in the matrix and negative (compressive) in the reinforcing particles. Internal elastic strains evolve in a similar behaviour in the unreinforced AZ31 and in both composites. However, the accumulated elastic strains are reduced in the case of the composite because a part of the applied load is borne by the ceramic particles. © 2009 Elsevier B.V.
