Abstract

This study produced Al₈₅Ni_12.5Si_2.5
alloy by
arc melting method. This alloy was annealed at four different temperatures (200 ºC, 300 ºC, 400 ºC, 500 ºC). After annealing alloys
analyzes were performed for microstructural, mechanical and thermal behaviour
properties of X-ray diffraction (XRD), scanning electron microscopy (SEM) and
differential thermal analysis (DTA).  The
XRD results crystalline phases a-Al,
Si, Al₃Ni and Al₃Ni₂ were detected. The SEM investigations showed the formation of a-Al,
Si and Al₃Ni. The DTA
curves the melting point temperature of Al₃Ni is to be as 574.8ºC. Mechanical properties of the
as-cast and subsequently the micro hardness values of sample annealed
at 300 ºC, 400 and 500 ºC were 135.8, 135.2 and 130 HV
respectively.
