Effect of strain rate on tensile and compression behaviour of Al–Si/graphite composite
چکیده انگلیسی

Effects of strain rate (10−4–10−2 s−1) on tensile and compressive strength of the Al–Si alloy and Al–Si/graphite composite are investigated. The strain hardening exponent value of the composite was more than that of the alloy for all strain rates during tensile and compressive loading. The yield stress of the composite was more than that of the ultimate tensile strength of the alloy for all strain rates. Tensile and compressive properties of the alloy and composite are dependent on strain rates. The negative strain rate sensitivity was observed for the composite and alloy at lower strain rates during the compression and tension loading respectively.


► The negative strain rate sensitivity was observed for the composite and alloy.
► Composite and alloy is behaved as sensitivity system with variation of strain rate.
► Strain hardening exponent value of the composite is more than that of the alloy.
