This study was undertaken with the objective of evaluating the effect of reinforcement volume fraction on the tensile properties of a SiC particulate- reinforced aluminium alloy MMC in the as-extruded condition. The material used in this investigation was powder metallurgy aluminium alloy 2124 reinforced with various volume fractions of SiC particulates. Three different volume fractions (20, 25 and 30 vol %) of SiC were chosen. The chemical composition of the ...
In this paper the low cycle fatigue, cyclic stress response characteristics and cyclic fracture behavior of aluminum alloy 2124 discontinuously reinforced with varying volume fractions of silicon carbide particulate is examined. the metal matrix composites were cyclically deformed over a range of strain amplitudes using tension-compression loading under total strain control, in controlled environment and microstructural condition. the 2124+sic(sub p) composite displayed cyclic hardening at all strain amplitudes and for ...
The work represents characterization of strain rate and environment influences on the tensile properties of an AISI 1018 steel having a fully spheroidized microstructure; the steel was received in the spheroidized condition; all tensile test specimens were oriented such that the longitudinal direction of each specimen was parallel to the rolling direction of the plate; so that, the gross fracture plane was perpendicular to the rolling direction in each case. ...
