1. DESIGN, CONSTRUCTION AND TESTING OF AN IMPROVED CASTING POURING LADLE
ABSTRACT
A ladle is a foundry tool or equipment specially designed to pour molten metal into a prepared mould. The pouring rate or consistency is one of the factors that may lead to a defect in a cast. To avoid casting defects (cold shut and misrun) associated with pouring, there is nee...
2. PERFORMANCE EVALUATION OF DIFFERENT MATERIALS AS CHILLS IN SAND CASTING OF ALUMINIUM ALLOY
ABSTRACT
This study has evaluated the effectiveness of metallic materials as chill in sand casting of aluminium alloy. Four plates of dimension 165mm x 80mm x10mm were cast using sand mould. Steel, copper and brass chills in form of cylindrical bar of g...
3. PERFORMANCE EVALUATION OF DIFFERENT MATERIALS AS CHILLS IN SAND CASTING OF ALUMINIUM ALLOY
ABSTRACT
This study has evaluated the effectiveness of metallic materials as chill in sand casting of aluminium alloy. Four plates of dimension 165mm x 80mm x10mm were cast using sand mould. Steel, copper and brass chills in form of cylindrical bar of geometry 7mm in diameter and 50mm l...
4. THE DEVELOPMENT OF Al-5%Cu/GRAPHITE PARTICULATE COMPOSITES FOR ENGINEERING APPLICATIONS
ABSTRACT
A method of preparing cast aluminium alloy – graphite particulate composite using uncoated graphite with the addition of 1wt% magnesium to aid wettability was studied. The method consists of introducing and dispersing uncoated but pre-treated graphite particles in alumini...
5. DEVELOPMENT OF CAR PISTON MATERIAL FROM ALUMINIUM ALLOY USING COCONUT SHELL ASH AS AN ADDITIVE
ABSTRACT
This research presents the development of a piston material from aluminium alloy using coconut shell ash as an additive. Most damage pistons reported in literature are as a result mechanical fatigue due to wear and thermal fatigue. Investigations revealed that aluminium alloys...
6. COMPUTER SIMULATION OF HEAT TREATMENT PROCESS FOR ALUMINIUM ALLOY
ABSTRACT
Temperature of aluminium alloy is simulated using MATLAB programming language for annealing, soaking to have uniformity of microstructure and quenching treatment processes. Workpiece selected for the study was aluminum alloy 6061-O, T1, T4 and T6 of different shapes: plate, cyl...
