Development of Castor Oil – Graphite Lubricants for Cold Extrusion of Aluminium Alloy
The study was conducted to develop castor oil – graphite lubricants for cold extrusion of aluminium alloy and to investigate the effect of the developed lubricant on the extrusion pressure of aluminium alloy. Cold extrusion process at a constant extrusion ratio of 1.25:1 was used on 14mm diameter by 30mm long aluminium alloy billets. Experimental results showed that onset pressure ranges from 1...
متن کاملExtrusion of 7075 aluminium alloy through double-pocket dies to manufacture a complex profile
Low-temperature incipient melting and high deformation resistance of aluminium alloy AA7075 place extraordinary demands on extrusion die design and process optimization, especially when the shape of the extrudate is complex. The present case study was aimed at combining the considerations on die design and process optimization for the alloy to manufacture a complex solid profile with large diff...
متن کاملPositron Lifetime Measurements of Subsurface Region in Aluminium Alloy and Aluminium Alloy Composite after Dry Sliding
This paper presents positron lifetime studies of the subsurface region of AK12 aluminium alloy and Al2O3-particle-reinforced AK12 aluminium alloy composite after sliding against steel in the pin-on-disc machine. The defect depth profile detected in the AK12 alloy extended up to 300 μm but for the composite AK12 the range of this profile was significantly shortened to less than ∼ 90 μm. The posi...
متن کاملEffect of Die Entry Angle on Extrusion Responses of Aluminum 6063 Alloy
Mechanical properties response of extruded 6063 aluminum alloy at varied die entry angle has been investigated. Plain carbon and tool steel dies with entry angles of 15, 30, 45, 60, 75 and 90 were simulated. Extrusion on the alloy was done at ambient temperature (37C) and the extruded samples from the various angles were subjected to selected service related mechanical tests and microstructural...
متن کاملEffect of quartz-silicon dioxide particulate on tensile properties of aluminium alloy cast composites
This paper describes an experimental investigation of the tensile properties of quartz-silicon dioxide particulate reinforced LM6 aluminium alloy composite. In this experimental, quartzsilicon dioxide particulate reinforced LM6 composite were fabricated by carbon dioxide sand moulding process with variation of the particulate content on percentage of weight. Tensile tests were conducted to dete...
