The Study of Functionally Graded Al-Si Alloy Fabricated by Centrifuge Casting Technique

Abstract

Functionally graded materials are plays very important role in engineering and other applications. They are class of designed materials described by a spatial variety of organization and microstructure going for controlling comparing utilitarian properties
(i.e. mechanical, thermal, electrical, etc). In this paper describes comparison of FGMs of Al-Si alloys fabricated through centrifuge casting technique. Al-Si alloys are characterized good strength, less weight, low corrosive and wear resistance, good weldability etc. Here we are fabricating Al-12%Si and Al-18%Si alloys through centrifuge casting (vertical centrifugal technique) for different pouring temperature of molten metal and constant mould rotation speed. For that we conclude results based on varying the addition of silicon percentage in base metal and increases pouring temperature, for that we got better mechanical properties and good microstructure features. These alloys are useful wherever good strength, light weight of materials is required.
