Hot Rolling of Flame Retardant Magnesium and Aluminum Alloys to Produce a Cladding Plate

Because of its lightweight and strength, aluminum alloys are used are being used increasing for the production of lightweight construction. In addition to applications in the expanding transportation market, aluminum sheet and foil materials are traditionally used for food and medical packaging, thin foil, and fin stock for air conditioners and heat exchangers, decorative panels and lithographic sheet. Rolling is a process used for the production of strip or sheet. In this article, rolling processing of aluminum and aluminum alloys is discussed in detail and specific processes include: hot-rolling, cold-rolling, and rolling of aluminum foils.

Parametric Studies

To determine the relations between rolling passes, mechanical behaviours and microstructure evolution of AA7050 aluminum alloys, finite element modeling of a multipass hot rolling process is developed and employed to investigate thermo-mechanical evolution during this processing. Through parametric studies, the distribution of local strain and temperature across thickness during the hot rolling process are numerically determined. These results are used to determine the subgrain size and thus the microstructure evolution during the hot rolling process are estimated.

Lithium Alloys

Aluminum-Lithium alloys are attractive choices for weight saving of aerospace structures. By addition of Lithium to Aluminum alloys, the mechanical and physical properties are improved, density decreases up to 10% and module of elasticity increases up to 15%. As-cast Al-Li ingots include some continues brittle phases in grain boundaries that decrease formability by crack initiation during hot rolling. In the present work, influence of homogenization on hot rolling of Al- Li alloys was studied. Homogenization temperature determined based on DTA test and homogeneity properties were characterized by microstructures observation. One specimen was cast in conventional method and the other was cast by direct casting (DC) method. Homogenization was performed at four different times: 10, 24, 50 and 100 hours at 500°C also no cracking has been observed in both ingots in 100 hr and 24 hr at 500°C respectively due to eliminate the brittle phases.
