Abstract
ABSTRACT In the present investigation, AA5052 metal matrix nanocomposites (MMNCs) reinforced with ZrAl3 particles were fabricated using an in situ reaction. The study focuses on the effect of variation in vol.% of reinforcement particles and reaction time on phases, microstructure and tensile strength. Potassium hexafluoro zirconate (K2ZrF6) salt was used for the fabrication of 3, 6, 9 and 12 vol.% of ZrAl3 particles in the matrix. The increase in wt.% of salt and reaction time increases the vol.% of ZrAl3 particles and distributes the nanoparticles homogeneously in the matrix, respectively. Tensile strength and yield strength improved with the increase in vol.% of ZrAl3 particles and increase in reaction time.
