Effects of ZnO coating of whiskers on the tensile properties and aging behaviors of aluminum borate whiskers reinforced 2024Al composite

Effects of metallic Ti particles on the aging behavior and the influenced mechanical properties of squeeze-cast (SiCp+Ti)/7075Al hybrid composites

“…6D). The formation of a slight interlayer can be also detected in other researches [1,26]. However, the interfaces between the Ti particles and the matrix alloy have great differences during the aging processes.…”

“…Efforts have been made to improve the usability of AMCs by many researchers. Among them, aging treatment is one of the most important ways to improve the usability of AMCs based on 2000, 6000 and 7000 series precipitation hardening aluminum alloys [1][2][3][4].…”

Thermal Kinetics of SiCp Reinforced AA7075 Alloy Composite

“…Plastic deformation, strains occurs as a result of the thermal mismatch, resulting in a high density of dislocations, particularly near the SiC particulates. The dislocation density (ρ) can be evaluated by equation (2). The previous research work [37] indicated that the growth of precipitates accelerated at the dislocations because dislocations create free path for the kinetically faster atomic transportation of precipitates comparative to majority transmission in a crystal.…”

“…The precipitation sequence of aluminum alloy is as follows: α -supersaturated solid solution (αssss) → GP zones (Zn, Mg) →ή (MgZn2) → η (MgZn2). Thermal treatment is the most significant method to increase the application area of AMCs which are based on precipitation hardening phenomenon [2][3][4][5]. Inspection showed that reinforcement in AMCs does not affect the sequence of precipitation formation but changes the precipitation kinetics of AMCs during the aging process [6,7].…”
