“…It was stated that the flow of the matrix around the particles in high pressure and temperature can improve the bond strength of the particles and matrix. 19 According to Fig. 2, due to the high strain hardened base metal, none bonded areas between the layers (white arrow) remained from the last two ARB cycles.…”

“…This mismatch is relaxed by the formation of geometrically necessary dislocations. 19,20 Moreover, because of the difference between the thermal expansion coefficient of aluminium and alumina, variation of temperature during the production process generates geometrical dislocations to accommodate the strain incompatibility around the particles. 24 The presence of more dislocations in the structure and interaction between them increases the workhardening of the composite rapidly.…”

Aluminium matrix composites reinforced with submicrometre and nanosize Al2O3 particles were successfully manufactured in the form of sheets through eight cycles of accumulative roll bonding process. The mechanical properties of the produced composite are compared with accumulative roll bonded commercially pure aluminium. It is shown that only 1 vol.- of submicrometre or nanosize alumina particles as reinforcement in the structure can significantly improve the yield and ultimate tensile strengths. Scanning electron microscopy revealed that particles have a random and uniform distribution in the matrix especially in the less volume fraction of alumina particles, and strong mechanical bonding occurs at the interface of the particle matrix. According to the results of the tensile tests, it is observed that with less alumina content, the composite reinforced by nanosize particles has higher strength than that by submicrometre size particles. However, more reinforcement up to 3 vol.- of submicrometre particles, as a result of including fewer microstructural defects, leads to better mechanical properties in comparison to the nanoparticle composite.

This paper presents a successful method to fabricate high-quality composite micro parts. The fabrication process starts with producing SU-8 aster moulds using photolithography technique, mirror replication of PDMS soft moulds, preparing composite slurry using super fine 316-L stainless steel (5 µm) and α-alumina powder (⩽400 nm) in 2.5, 5, 7.5 and 10 wt%, filling the moulds, obtaining the green parts, de-binding and sintering. A new method was used in this research to homogenize the alumina particles in a stainless steel composite slurry. Stainless steel and alumina powders were dispersed separately in distilled water and dispersant. Then, the two dispersed powders were mixed together to form a homogeneous composite slurry. The process resulted in high-quality composite micro parts which retain the very details of the SU-8 master moulds. The internal structures of the green and sintered micro parts showed homogeneous distribution of alumina particles in a stainless steel matrix. The density and micro hardness of the sintered parts were also investigated in detail for different stainless steel alumina compositions.
