Fatigue and Anisotropic behaviours of cold rolled AA1200 Aluminium Alloy
This study examines the fatigue and anisotropy behaviour of cold rolled AA1200 aluminium alloy for light weight automotive connecting rod application. Aluminium (Al) 1200 ingots were melted at temperature of 680 0C (after one hour of heating) cast in sand mould and cast samples homogenized for 6 hrs at 480 0C. The cold rolling process was carried out after homogenisation for 10, 20, 30, 40 and ...
متن کاملEvaluation of Mechanical Properties of Aluminium Alloy AA 6061(HE-20)
The general manufacturing objective during the fabrication of automotive, structural and aerospace components, particularly through flow forming process is to achieve predefined product quality characteristics and mechanical properties with process cost and time constraints. The current state of the economy and the consequent market pressure has forced vehicle manufacturers to simultaneously re...
متن کاملImprovement of thickness tolerances For a two-stand aluminium cold rolling mill
trol loops to compensate backup roll eccentricity and harmonic hardness variation allows a significant improvement in strip thickness performance. These measures were successfully implemented as an extension to an exist ing two-stand aluminium cold rolling mill. An essential quality characteristic in the cold rolling sector is the minimum thickness deviation that can be achieved at final gauge,...
متن کاملDevelopment 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 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...
