Patent number: 12104237Abstract: This invention discloses a series of low-cost, castable, weldable, brazeable and heat-treatable aluminum alloys based on modifications of aluminum-manganese-based alloys, which turn all the non-heat treatable Mn-containing aluminum alloys into heat treatable alloys with high-strength, ductility, thermal stability, and resistance to creep, coarsening and recrystallization. These alloys inherit the excellent corrosion resistance of the Al—Mn-based alloys and can be utilized in high temperature, high stress and a variety of other applications. The modifications are made through microalloying with one or any combinations of tin, indium, antimony and bismuth at an impurity level of less than 0.02 at. %, which creates nanoscale ?-Al(Mn,TM)Si precipitates with a cubic structure (wherein TM is one or more of transition metals, and Mn is the main element) in an Al(f.c.c.)-matrix with a mean radius of about 25 nm and a relatively high volume fraction of about 2%.Type: GrantFiled: February 14, 2022Date of Patent: October 1, 2024Assignee: NORTHWESTERN UNIVERSITYInventors: Amir Rezaei Farkoosh, David C.

The Al—Zn—Mg—Sc alloys may optionally include other alloying additions such as Cu, Mn, Zr, Ti and the like. The alloys possess good properties such as relatively high strength and excellent corrosion resistance. The alloys may be fabricated into various product forms such as extrusions, forgings, plate, sheet and weldments.Type: ApplicationFiled: February 1, 2006Publication date: March 18, 2010Inventor: Timothy Langan
