“…Hashish’s 11 work reported that selection of machining parameters is highly important in AWJM to avoid formation of burrs, cracks, and delamination and for good surface quality, as well as kerf behavior. A vast amount of work has investigated the performance of AWJM on various materials, notably Mardi et al, 12 which investigated the effect of AWJM on the surface quality of Mg-based nano composites. Karakurt et al 13 studied the performance of AWJM on cutting the granites; experimental results proved the effectiveness of machining on kerf angle.…”

Composite materials have taken an imperative place in the material system because of their unique performance in various specialized applications. Fiber inclusion and the heterogeneous property of composites make it more difficult to machine with the conventional machining process. However, several nonconventional methods have been adopted for machining composites, in which abrasive water jet machining (AWJM) was proven to be more effective and a preferable technique in machining of fiber-reinforced composite material. This review article is intended to highlight and categorize the machining performance of the fiber-reinforced composites on machining with AWJM process.

“…However, magnesium-based materials suffer from low corrosion resistance, low ductility and modulus of elasticity, low abrasion resistance and poor creep resistance which limits their use in structural applications. These limitations can be circumvented by the development of new magnesium-based composites and nanocomposites [1,[3][4][5]. Mg-based alloys and composites are well-addressed by many researchers for improving the mechanical properties along with ductility.…”

In this study, Mg-6Al/Al2O3 nanocomposites were synthesized using disintegrated melt deposition technique followed by hot extrusion. Two different amounts of alumina nanoparticles (0.66 and 1.11 wt.%) were added into Mg-6Al matrix. Microstructure and mechanical properties were investigated. Results of XRD analysis revealed that the presence of alumina nanoparticles assisted in randomization of texture (basal to prismatic). The compressive response regarding hardness and compressive strength was assessed using nanoindentation and compressive tests. The results of hardness, modulus of elasticity, compressive strength and the deformation behavior of the composites were compared with pure Mg and Mg-6Al alloy. In all the cases, the composites exhibit better mechanical properties.K e y w o r d s : Mg-6Al alloy, Al2O3 nanoparticles, microstructure, compression, nanoindentation

“…The only drawback of AWJM is lesser efficiency in creating highquality surfaces which can be expected from the other two methods. Bimla Mardi et al [29] investigated the surface integrity of Mg-based nanocomposites generated by AWJ. Feasibility of AWJ in machining Mg-based nanocomposites was reported.…”

Mg-based materials are considered to be the most machinable of all materials due to their good machinability. Though conventional machining of Mg-based materials is a topic that has been widely discussed, they are associated with ignition issues. Ignition risk in conventional machining of Mg-based materials thus cannot be denied and should be avoided. Literature has witnessed ignition risk when machining temperature reaches above 450°C during turning and milling processes, and some cases are reported with fire hazard. In order to obtain the safest machining atmosphere, abrasive water jet machining, a most desired machining technology for machining Mg-based materials, is discussed in the present chapter. The text covers ignition risk in conventional machining of Mg-based materials, an overview of non-traditional methods for machining Mg-based materials, advantages of abrasive water jet machining over other methods, abrasive water jet linear cutting of Mg alloys and composites, and drilling of Mg alloys. Experimental investigations are carried out to know the effect of abrasive water jet process parameters on machining Mg alloys and Mg nanocomposites. Surface topography of cut surfaces is analyzed. Suitability of abrasive water jet in drilling Mg alloys is justified by comparing results with holes drilled by conventional drilling and jig boring.
