INFLUENCE OF HOT EXTRUSION ON MECHANICAL CHARACTERISTICS OF AL6063-TIC METAL MATRIX COMPOSITES

Of all the aluminium alloys Al 6000 series is quite popular choice has a matrix material to prepare metal matrix composites owing to its better formability characteristics and option of modification of the strength of composites by adopting optimal secondary processes. The simplest and commercially used technique is the vortex or stir casting technique for casting process. The various reinforcements that have been tried out to develop the metal matrix composites are graphite, silicon, carbide, titanium nitride, tungsten, boron Al2O3, fly ash, Zr, Si3N4, TiB2, etc. Further meager information is available in the literature as regards the Mechanical properties of TiC reinforced with Al6063 base metal matrix composites. Hence, the present investigation is aimed at developing aluminium metal matrix composite consisting of Titania reinforcement in Al6063 alloy and to characterize the effect of reinforcement on Mechanical properties in as cast and as extrusion
