Aluminum 2024 and 7075 alloys which are widely used in aerospace and marine applications were chosen to investigate their strengthening mechanisms. Using differential thermal analysis (DIA), metallography and tension tests, the best solutionizing conditions were determined to be 500±5°C and 2 hours for 2024 and 480?±5°C and 1 hour for 7075 alloy. Aging was performed in the range of 100 to 200°C...

In this study, B4C+SiC/B4C +TiB2/SiC+TiB2 hybrid reinforcements were added to Al 7075 matrix via the powder metallurgy method. The powders subjected mechanical grinding for 240 min, as shown in graphical abstract. composite structure produced by was then placed a vertical casting chamber and molten (main matrix) obtain samples. Samples dissolved 1 h at 480 ?C, aged 120 ?C 4-h increments (32 tot...

Vaporizing foil actuator welding (VFAW), an impact method, was used for the first time to produce high strength welds between SiC-reinforced 8009 aluminum metal matrix composite (MMC) (8009/SiC/11p) and 7075 alloy (AA7075). Microscopic characterization of dissimilar weld revealed multiple heterogenous microstructural zones including unbonded zone at center, a flat interface, wavy trapped jet co...

Abstract This work employs an example of a through process experiment systematic approach to study the relationship among powder properties, cold spray (CS) processing parameters, and consolidated specimen behavior combined effort characterization methods computational models. will allow for isolation variables that can affect CS deposit properties. In this study, Al 7075 was used as feedstock ...

In the last decades, many catastrophic events due to rupture of metallic components have been traced back fretting fatigue. order avoid failures such a contact phenomenon, researchers focused on fatigue behaviour different materials. present work, an experimental campaign carried out Al 7075-T6 aluminium alloy is simulated by employing multiaxial criterion proposed for The configuration flat-to...
