چکیده انگلیسی
This study estimates the effects of grain refinement on the transformation kinetics of precipitates as well as the development of mechanical properties and electrical conductivity of CuNi3Si1Mg. During aging at 450 °C, the mechanical behaviors of coarse-grained (CG) CuNi3Si1Mg and ultrafine-grained (UFG) CuNi3Si1Mg were studied and the Avrami-equations of phase transformation kinetics and electrical conductivity were analyzed. For both the conditions, the maximum strength was observed at 6 and 12 h, for UFG and CG CuNi3Si1Mg, respectively. According to the transformation kinetics curves of CG and UFG CuNi3Si1Mg, over aging reduced the growth rate of precipitates and affected their coarsening, resulting in decreased strength.
