Abstract Scope |
Al alloys often have inherently low mechanical strength and limited operation temperature. Most Al alloys have mechanical strength of 200-500 MPa, and soften rapidly at low homologous temperature. We have used magnetron sputtering to fabricate various nanotwinned Al supersaturated solid solution alloys. We will discuss the deformation mechanisms of these nanotwinned Al alloys at room temperature and their high temperature thermal and mechanical stability. The plastic deformability of nanotwinned Al alloys has been evaluated in tension and compression. DFT calculations and microscopy studies reveal the fundamental mechanisms of high temperature stability and exceptional mechanical strength in these nanotwinned Al alloys. |
