Abstract
System and method of producing multi-layered aluminum alloy products are disclosed. A multi-layered aluminum alloy product may be formed by first heating a first aluminum alloy to a first temperature where the first temperature is at least about 5° C. lower than the eutectic temperature of the first aluminum alloy, second heating a second aluminum alloy to a second temperature where the second temperature is at least about 5° C. higher than the liquidus temperature of the second aluminum alloy, and coupling the second aluminum alloy to the first aluminum alloy to produce a multi-layered aluminum alloy product.
Claims20
A method comprising:
- first producing a first aluminum alloy;
- first heating the first aluminum alloy to a first temperature, wherein the first temperature is at least about 5° C. lower than the eutectic temperature of the first aluminum alloy;
- second producing a second aluminum alloy;
- second heating the second aluminum alloy to a second temperature, wherein the second temperature is at least about 5° C. higher than the liquidus temperature of the second aluminum alloy;
- and
- placing the second aluminum alloy and the first aluminum alloy in contact, wherein the placing comprises producing a first multi-layered aluminum alloy product.
A multi-layered aluminum alloy product comprising:
- a first aluminum alloy coupled to a second aluminum alloy, wherein the coupling is accomplished by:
- first heating the first aluminum alloy to a first temperature, wherein the first temperature is at least about 5° C. lower than the eutectic temperature of the first aluminum alloy;
- second heating the second aluminum alloy to a second temperature, wherein the second temperature is at least about 5° C. higher than the liquidus temperature of the second aluminum alloy;
- and
- contacting the second aluminum alloy to the first aluminum alloy.
A multi-layered aluminum alloy product comprising:
- a first aluminum alloy coupled to a second aluminum alloy, wherein the coupling is accomplished by:
- first heating the first aluminum alloy to a first temperature, wherein the first temperature is at least about 5° C. lower than the eutectic temperature of the first aluminum alloy;
- second heating the second aluminum alloy to a second temperature, wherein the second temperature is at least about 5° C. higher than the liquidus temperature of the second aluminum alloy;
- first contacting the second aluminum alloy to the first aluminum alloy;
- and
- a third aluminum alloy coupled to the second aluminum alloy, wherein the coupling is accomplished by:
- third heating the first and second aluminum alloys to a third temperature, wherein the third temperature is at least about 1° C. lower than the lesser of the eutectic temperatures of the first and second aluminum alloys;
- fourth heating the third aluminum alloy to a fourth temperature, wherein the fourth temperature is at least about 5° C. higher than the liquidus temperature of the third aluminum alloy;
- and
- second contacting the third aluminum alloy to the second aluminum alloy.
