Abstract The present work, reviews the mechanical and microstructural analyses, of copper and silicon carbide reinforced
recycled aluminium matrix (Alumix 431) composites manufactured by sinter+forging technique. Static compression, impact
tests and also scratch damage tests were carried out. Detail analyses of Scanning Electron Microscopy (SEM) supported by
XRD, thermal and electrical conductivity measurements have been carried out on the specimens before and after the tests.
The results exposed that, the composites have homogeneous structure without porosity and very homogeneous distribution
of fine silicon carbide (SiC) particles. The failure damage in composites occurs in both matrix and particles implying good
chemical bonding diffusion between matrix and particles. This composite will be applied on the pieces with high thermal
conductivity and high surface damage resistant.
7.1 Introduction
In most of the different industrial applications, high surface resistance performance and thermal conductivity are great
importance [1–4]. In these applications, high performance lightweight materials and robust structural requirements cause
development in manufacturing methods [5–11]. In this context, Aluminum-Copper elements provide low weight parts and
thermal conductivity with high performance microstructure. However, these composites always need to be reinforced with
hard, many times fine ceramic type particles. For this reason, the production process that we call combined sinter + forging
used to manufacture the aluminium-based composites can offer many advantages in processing and lower manufacturing costs
as these composites are produced from recycled constituents known as fresh scrap materials [8, 11–15].
New family of aluminium-based composites are extensively used in the aerospace industries doped with different metal
and ceramic reinforcements to improve their mechanical and tribological properties [1–8]. A ceramic reinforcement such as
SiC when added to the aluminium matrix can improve the mechanical properties and wear resistance of these composites.
Addition of copper reinforcement together with Silicon Carbide (SiC) can give a good combination of high ductility and the
high strength [9–15].
