Effect of in-situ reaction time on the strength of AA5052/ZrAl₃ metal matrix nano composites

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.
