Developing high strength Al-Zn-Mg alloys by thermomechanical treatments

Abstract 

For the first time, the formation and impact of (Al, Zn)3Zr precipitates in Al-Zn-Mg-Cu alloys post-heat treatment was detailed, offering new insights into mechanical property enhancement through these discoveries. In addition, research introduces grain boundary deposition engineering as a novel method to develop aluminium alloys with specific precipitate types and mechanical properties, aiming for industrial application viability.
