We have determined the macroscopic plastic deformation behaviour of high-quality single-crystalline samples of the complex metallic alloy beta-Al-Mg. Uniaxial deformation experiments at a constant strain rate of 10(-4) s(-1) were performed at temperatures between 200 and 375 degrees C. The material exhibits ductile behaviour down to temperatures of 225 degrees C. At this temperature an upper yield stress of 780 MPa was observed, which is a very high value compared to commercial Al-Mg alloys. The upper yield point is followed by an almost constant flow stress level up to strains of about 6%. Stress-relaxation tests and temperature changes were carried out in order to determine the thermodynamic activation parameters of the deformation process. (C) 2006 Elsevier Ltd. All rights reserved. |
