“…In some aluminum alloys, hard particles in proportions of up to 15 % vol. and aging processes, provided the latter do not cause coalescence of the precipitates, may reduce cutting forces by at least 10 % [17,18].…”

“…Increasing the cutting speed normally reduces the machining forces, regardless of the strength of the aluminum alloy [11,17,18], since the shear stress in the primary shear zone and in the flow zone at the secondary shear region decreases with increasing cutting speed due to an associated increase in cutting temperature [19,20]. Although high cutting speeds contribute to lowering machining forces, in high-speed cutting (HSC), excessive increase in deformation rates may increase the machining forces (fig1) The cutting force, and therefore the power, required to machine aluminum is less than might be expected on the basis of its mechanical properties.…”

The use of aluminum alloys in manufacturing industry has increased significantly in recent years. This is because primarily to their ability to combine lightness and strength in a single material. Concomitant to this growth, the machining of aluminum alloys has enormously increased in volumetric proportionsso that the chip volume represents up to 80 % of the original volume of the machined material in certain segments of the industry, like aerospace. In this context, knowledge of the characteristics of machinability of aluminum alloys is essential to provide industry and researchers with information that allows them to make the right decisions when they come to machining this fantastic material. The purpose of this review is to compile relevant information about the characteristics of machinability of aluminum alloys into a single document.

Abstract:The conjoint influence of welding and artificial aging on mechanical properties were investigated for extrusions of aluminum alloy 6063, 6061, and 6005A. Uniaxial tensile tests were conducted on the aluminum alloys 6063-T4, 6061-T4, and 6005A-T1 in both the as-received (AR) and as-welded (AW) conditions. Tensile tests were also conducted on the AR and AW alloys, subsequent to artificial aging. The welding process used was gas metal arc (GMAW) with spray transfer using 120-220 A of current at 22 V. The artificial aging used was a precipitation heat treatment for 6 h at 182˝C (360˝F). Tensile tests revealed the welded aluminum alloys to have lower strength, both for yield and ultimate tensile strength, when compared to the as-received un-welded counterpart. The beneficial influence of post weld heat treatment (PWHT) on strength and ductility is presented and discussed in terms of current design provisions for welded aluminum light pole structures.

“…In-situ composites have overcome these problems because of the formation of reinforcements by exothermal chemical reaction. The 6061 aluminum alloy has been used in automotive industry for the fabrication of parts which includes wheel, panels and vehicle structure [5] ZrB 2 is known to have many superior properties such as high melting temperature, hardness, corrosion resistance, oxidation resistance and electrical conductivity, being used for aircraft / rocket components working at special high temperature, cutting tools and cathode material for aluminum refinement furnace [6]. Production of in-situ metal matrix composite by flux assisted synthesis was widely reported in the literatures [7][8]10].…”

Abstract. Aluminum matrix composite is the innovation of high performance material technology and it has superior interfacial integrity and thermodynamic stability between the matrix and reinforcement. Making the engineering components from this composite material require subsequent machining operations. This paper presents the detailed experimental investigation of the machining behaviour in turning of Al 6061-7.5% ZrB 2 Metal Matrix Composite (MMC) by using Poly Crystalline Diamond (PCD) insert of 1600 grade. The effect of ZrB 2 reinforcement particles on machinability behaviour need to be studied. It is concluded that the feed rate has great influence on surface roughness and depth of cut has great influence on cutting force. The confirmation experiment indicates that there is a good agreement between the estimated value and experimental Value. Tool wear study also carried out for time duration of 15 minutes.
