Structural Non-Homogeneities Analysis of Zn-22 Wt. % Al Alloy by Nano-indentation
Journal Title: RECENT - Year 2015, Vol 16, Issue 45
Abstract
In the present paper the structure and properties of different phases/constituent of the eutectoid Zn-Al based alloys obtained by gravitational casting in brick moulds have been investigated. The microstructural analyses were performed by scanning electron microscopy which was followed by energy dispersive X-ray spectroscopy analysis. Nano-indentation testing has been used to determine the phase/constituents mechanical properties like elastic modulus and hardness for a 22 wt. % Al alloy composition. The structural analysis and the nano-indentation results have revealed the intensity of the segregation phenomena during alloy solidification at smaller cooling rates.
