Processing of high strength EN AW 6082 forgings without a solution heat treatment

Enhancement of the Young’s Modulus through Infrared Heat Treatment: A Study of the Microstructure and the Mass Effect of Real Body 6082 Aluminum Forgings

“…It should also be noted that these Al(FeMnCr)Si intermetallic compounds aligned the original extruded rod in the long axis direction. Previous studies have shown that these permutations may affect the grain size and Mg 2 Si precipitation location [3]. Figure 8 shows the results of the SEM observation of the S forgings, where many white intermetallic compounds could be found in the Al matrix.…”

“…In this study, Al(FeMnCr)Si intermetallic compounds could be found in large dimples. In the case of the small dimples, based upon research and the XRD results, it could be concluded that the small dimples were caused by the fine Al(FeMnCr)Si phase and precipitates (Mg 5 Si 6 and Mg 2 Si) [3,15]. In addition, the dimples on the LAir specimen were more uniform in size than the dimples on the L180-6H, L190-1H, and L190-2H specimens.…”

“…Most automobile suspension components are manufactured using a high temperature forging process [2,3]. The alloy forging process is conducted with an extruded bar and the use of pressure to shape it into the required form under a set temperature condition.…”

“…Nowadays, according to previous studies, the coarse grain formed during the forming process can easily become coarser after the air furnace solution treatment process, which has been a thorny problem and has greatly affected the development of the 6082 aluminum alloy forging industry [2,3]. Grain coarsening is affected by the heat treatment time and temperature; hence, an infrared (IR) heat treatment was used in this study.…”

Mechanical and corrosion resistance properties of AA7075-T6 sub-zero formed sheets

“…1 Introduction 7xxx series aluminium alloys are characterized by a very attractive combination of low density, high specific strength and corrosion resistance. Actually, they are more and more used for lightweight structural components in the automotive and aerospace industries, in which weight savings for reduced fuel consumption and exhaust emissions are mandatory [1]. However, their adoption for manufacturing sheet components is greatly limited by their scarce formability [2], and rapid degradation when exposed to the in-service environment that deteriorates their mechanical properties [3].…”
