Hybrid metal matrix composites (HMMCs) are the composites of the second generation that are much needed to meet the need for advanced engineering. Among these,
aluminum hybrid metal matrix composite (AHMC) is one of the HMMCs in which
we can produce suitable materials [2].
AHMCs are produced using the powder metallurgy (P/M), mechanical alloying,
casting methods such as stir, compo and squeeze casting and spray deposition method
[3]. Among these, P/M has a low processing temperature compared to casting phase,
which prevents undesirable reactions between reinforcements and matrix, as well as
near-net-shaped parts. P/M has control over pore size, number of pores and phase
distribution due to compaction of powders and sintering conditions [4, 5].
Anandpratheepan et al. investigated that TiB 2 particles will not be subjected to
any reaction with the aluminum matrix, thereby preventing the development of brittle
existence in the composite Al metal matrix. TiB 2 has good thermal conductivity and
stability, high youth modulus and electrical conductivity, low specific gravity and
superior wear characteristics that make the TiB 2 suitable for hybrid reinforcement
[6]. Gajakosh et al. also reported that the Al7075-based composite microstructure
reinforced with TiB 2 showed a homogeneous distribution of reinforcements with
superior matrix Al 7075 [7].
Penchalreddy et al. studied when Al–Cu–Li particle reinforced composite fabricated through P/M route involving microwave sintering and hot extrusion (HET).
In their investigation, they found that ductility, yield strength, ultimate tensile and
compression strength, Young’s modulus and microhardness are increased due to
uniformly distribution of hard and brittle particle of alumina reinforcement phase in
ductile Al matrix [8]. Sajjad sattari et al. investigated in a micron-sized Al matrix was
reinforced with nano-sized SiC particles through P/M and HET. They inferred that
550 °C temperature is an apt temperature for HET at which yield strength enhanced
by 75% and hardness by 40% due to presence of nano-SiC reinforcements [9].
Senthilkumar et al. manufactured various composite by using aluminum alloy
AA2014 with micro and nano-sized Al 2 O 3 particle ranging from 1 to 10 wt% through
powder metallurgy method and hot extrusion method at 550 °C temperature. They
revealed that composites have combination of 8 wt% of micron Al 2 O 3 and 2 wt%
of nano-Al 2 O 3 having better hardness than the other combinations [10]. C. E. da
costa et al. reported that when aluminum alloy (AA2014) reinforced with the nickel
aluminide through powder metallurgy route increases wear resistance two to three
times than base alloy [11].
Chandrasekar et al. analyzed microstructure, hardness, tensile properties and
corrosion properties of stir casted AlMg4.5 with various proportions of ceramic
alumina particles. Reinforced nano-alumina particles of 6 wt% improved their
corrosion properties due to exposure of NaCl solution. The tensile strength has
also improved with same reinforced due to the stress transformation [12]. Shrivanimoghaddam et al. revealed when Al reinforced with B 4 C, TiB 2 , ZrSiO 4 in
which ceramic/aluminum composite can withstand load due to interfacial bonding
between them. An effective interfacial bond shifts the load from matrix to reinforcements without any failures which determine physical and mechanical properties of
composites [13].
