PurposeThis study aims to investigate and model interrelationships between process parameters, geometrical profile characteristics and mechanical properties of industrially extruded aluminum alloys.Design/methodology/approachStatistical design of experiments (DOE) was applied to investigate and model the effects of eight factors including extrusion ratio, stem speed, billet-preheat temperature, number of die cavities, quenching media (water/air), time and temperature of artificial aging treatment and profile nominal thickness on four mechanical properties (yield strength, ultimate tensile strength, percent elongation and hardness). Experiments were carried out at an actual extrusion plant using 8-in. diameter billets on an extrusion press with 2,200 ton capacity.FindingsMain factors and factor interactions controlling mechanical properties were identified and discussed qualitatively. Quantitative models with high prediction accuracy (in excess of 95%) were also obtained and discussed.Practical implicationsThe obtained results are believed to be of great importance to researchers and industrial practitioners in the aluminum extrusion industry.Originality/valueAll practical and relevant parameters have been used to model all important mechanical properties in a collective manner in one study and within actual industrial setup. This is in contrast to all previous studies where either a partial set of parameters and/or mechanical properties are discussed and mostly under limited laboratory setup.

“…Aluminum composites are used in different applications few of them are Pistons, brake plate and cylinder and so on [1]. Aluminum composite increases the particulate reinforcement increases the strength by following traditional methods [2,3]. SiC is most normal molecule utilized in aluminum alloy composites [4,5] for light weight applications by addition of clay particles in the matrix the strength of the composite increases [6] Al6061 combination is warm treatable and subsequently additionally increment in quality can be normal [7], heat treatment process improves the strength and fit to design the material for industries [8].…”

“…Although they possess desirable mechanical properties, fiber reinforcement composites exhibit anisotropic behavior and are not easily produced by conventional techniques. Whereas MMCs reinforced with particles offer modest enhancement of properties they are more isotropic and can be processed by conventional routes [9,10]. AlSiC have thermal conductivities (170-200W/MK) that are compatible with maximum thermal energy dissipation for IC devices [11][12][13].…”

This paper studies the influence of the grit size of silicon carbide particles on the mechanical and electrical properties of stir cast aluminum matrix composites. A two step-mixing method of stir casting technique at (500 rpm) has been adopted. Type 1170 Al with (99.66 % C.P) and silicon carbide (SiC) particulates of 240 grit size (45 μm), 320 grit size (29 μm), 600 grit size (9 μm) and 1200 grit size (3 μm) were used. The incorporation of weight fraction of SiC ranges from 2.5 %, 5 %, 7.5 % and 10 %. The microstructures of the produced composites were examined using a scanning electron microscope. Mechanical properties were determined by using a universal testing machine of 30 KN load. Microhardness was performed on the composite specimens by using a LECO 700 HT tester with a load of 492.3 N and with a dwell time of 10 seconds. The electrical properties were determined using a Keithley instrument Model 2400 point probe machine. The results show that the modulus, yield strength and hardness of the composite increase at lower grit sizes of silicon carbide of 3 micron. The maximum hardness of 26.1 HVN and maximum modulus elasticity of 1517.6 N/mm −2 was obtained O. S. I. Fayomi at 7.5 % weight fraction of SiC. A boost in the mechanical and electrical properties of the produced alloys was gained by changing the grit size of the silicon carbide.
