Experimental Investigation on FSPed AZ91 Magnesium Alloy with Hybrid Reinforcement

Abstract

This study focuses on evaluating the Friction
Stir Processing (FSP) method when applied to
the magnesium alloy AZ91, in conjunction
with a hybrid reinforcement strategy.
Magnesium alloys are widely recognized for
their lightweight properties, making them
appealing for various applications. However,
they often suffer from weaknesses and poor
wear resistance. To address these issues, this
research explores the potential enhancements
that FSP can offer. FSP is a solid-state
processing method renowned for its ability to
improve mechanical properties and alter
microstructures in materials.
In this study, a hybrid reinforcement
approach is employed to further enhance the
performance of the AZ91 magnesium alloy.
This approach involves carefully selecting and
combining multiple reinforcing materials,
such as nanoparticles and particulate matter.
The aim is to increase the mechanical
strength, wear resistance, and overall
performance of the alloy.
The research follows a rigorous approach,
including the optimization of FSP process
parameters, to create hybrid-reinforced AZ91
specimens. The microstructural, mechanical,
and tribological properties of these specimens
are thoroughly examined. State-of-the-art
characterization techniques, including
microscopy, X-ray diffraction, and
mechanical testing, are used to assess the
effects of hybrid reinforcement and the FSP
process on the alloy.
The expected outcomes of this research
include a comprehensive understanding of the
microstructural changes induced by FSP, the
impact of hybrid reinforcements on
mechanical properties, and the overall
improvements in the performance of the
AZ91 magnesium alloy. These findings have
the potential to pave the way for the
utilization of magnesium alloys in industries
that require lightweight yet high-performance
materials. The research provides valuable
insights into developing hybrid reinforcement
procedures and optimizing FSP parameters to
enhance the features of magnesium alloys,
ultimately advancing their applicability in
various industrial sectors.
