The chapter presents the results of experimental investigation of the machinability of difficult to cut materials, e.g. silicon carbide particulate, aluminium metal matrix composite, cemented carbides layers, technical ceramics (Si 3 N 4). The work focuses on the study of machinability during conventional and laser-assisted turning. Nowadays, the difficult to cut materials have a great application in different fields of industry, e.g. automobile or aerospace. Metal matrix composites are known as the difficult to machine materials, because of the hardness and abrasive nature element-in this case-SiC. The work reported concentrates on the machinability improvement of difficult to cut materials by laser-assisted machining (LAM) when compared with conventional cutting process. Influence of laser beam during laser-assisted turning on temperature of the heating area, tool wear, and machined surfaces' roughness was investigated. This research was carried out for polycrystalline diamond wedges (PCD), ceramics and sintered carbide wedges with coatings and uncoated ones. The results obtained with the laser assisted machining were compared with results obtained in conventional turning.

“…It can be concluded that, with the adding of the content of La, there is a significant difference in the grain refinement effect. The microstructure of as-cast AlSi5Cu1Mg alloy consists of a wide range of intermetallic phases such as α-Al, Al 4 Fe, γ-Al 3 FeSi, α-Al 8 Fe 2 Si, β-Al 5 FeSi and Al 12 FeMnSi phase [25]. The matrix α-Al of as-cast AlSi5Cu1Mg alloy exhibits coarse dendrites and irregular shapes of clutter (Figure 2a).…”

“…Recently, many secondary phases have been added into aluminium alloys to fabricate aluminium matrix composites with high wear resistance [8][9][10][11]. Altınkök [12] reported that fine Al 2 O 3 /SiC particles were propitious to the effects on the tribological properties of Al-based composite. Selvi et al [13] found that the fly ash particles improved the wear resistance of the aluminium based metal matrix composites because the hardness of composites increased as the fly ash content was increased.…”

Abstract:The effects of 0, 0.3, 0.6 and 0.9 wt % modifier La on the dry sliding wear behaviours of AlSi5Cu1Mg alloy were investigated under different friction conditions (normal loads, sliding velocities) by using pin-on-disc configuration. The microhardness of the alloys was tested, and it was found that the microhardness of the alloys was improved by the La addition. The AlSi5Cu1Mg + 0.6 wt % La alloy exhibited the smallest grain size and maximum microhardness. The wear mechanism analysis of the worn surface was done, which drew support from a scanning electron microscope (SEM) that was equipped with an energy dispersive spectrometer. The results showed that AlSi5Cu1Mg + 0.6 wt % La alloy exhibited the best wear resistance, which was mainly due to the modified grain and microhardness. At the sliding velocity of 0.19 m/s, the adhesive wear became the main wear mechanism with the increase of the load because of the rupture of the oxide layer on the friction surface. Under the load of 3.8 MPa, the abrasive wear became slight as the sliding velocity increasing, due to the recrystallization phenomenon that happened in the frictional surface.

“…Many studies have been carried out on the static or quasi-static mechanical properties of discontinuously reinforced AMCs in the few decades [80][81][82][83][84][85]. The effect of strain rate working on the mechanical response of AMCs reinforced with particles has attracted less attention.…”

The microstructure and properties of Al-matrix composites are directly determined by ceramic particles in the matrix, such as synthetic methods, morphologies, sizes, interface, etc., especially the distribution of particles. Hereinto, Al-matrix nanocomposites, which show brilliant, comprehensive properties, have been widely studied. How to give full play to its advantages in further applications in automotive and aerospace areas has attracted considerable attention from researchers. In this review, current development on the pre-distribution of reinforcement particles and deformation processes and microstructure, mechanical properties of Al-matrix composites reinforced with in-situ and ex-situ nanoparticles will be addressed. In addition, the corresponding development prospects and challenges of nanoparticles reinforced Al-matrix composites fabricated by a combination of pre-distribution and deformation were also summarised.
