Fabrication of an Al/(Al2O3+AlxVy) In-Situ Composite: Investigation of Phase Evolution, Microstructural and MechnicalPropertice

In this Reaserch fabrication of anAl/ (Al2O3+AlxVy) in-situ compositevia mechanical-thermal activations in an Al–V2O5 system has been investigated. For this PurposethemixedpowdersofAlandV2O5 with different weight ratios (C1: Al-22. 93wt%V2O5 and C2: Al-15. 78wt%V2O5) ball milled and then compressed. Rawsamplesat temperatures650 ºC، 850 ºC and1000 ºC were heated. XRDanalysisof thesamplessinteredat temperature 1000 ºC showed that thephasesAl21V2، Al3Vandα-Al2O3formedinbothsampleas thereinforcmentthe diffrence thatthesamplesC1، also there isphaseAl45V7. compressive strength and strain of both composite samples Proportion with pure aluminum show a significant increase that knew due Presence of ceramic and Al-V intermetallic reinforcment particles and also were sintering of sample in presence of molten aluminum.
