The development of precipitate during ageing treatment of A319 alloy contributed significantly to the alloy strengthening mechanism. Two solution treatment temperatures which were set at 510°C and 525°C were subjected onto the different groups of A319 alloy samples and followed by artificial ageing process at 180°C. Scanning electron microscopy was employed to observe the over-aged samples from both solution treatment temperatures. The observation shows that Mg2Si precipitates was only appeared at the higher solution treatment condition, while the Al2Cu precipitate developed in both solution treatment temperatures.

Carbon fibers are produced from natural sources of water hyacinth plants that have been dried, ground and sieved to three different particle sizes of 600 μm, 300 μm and less than 300 μm. Through the analysis of data obtained from Differential Thermal Analysis (DTA) and Thermal Gravimetric Analysis (TGA), pyrolysis process was carried out at three different temperatures that is 320 ° C, 330 ° C and 350 ° C. Effect of different pyrolysis temperature on the properties of carbon fibers produced have been studied using Scanning Electron Microscope (SEM) analysis method. Results of SEM observed the carbon of the smallest particle size give the best structure and texture of surface morphology for optimum pyrolysis temperature of 330°C.

In this project, iron mill scale has been used to produce iron powder that can be used within the Powder Metallurgy process. To achieve this objective, the iron mill scale needs to be refined. This involve the work of grinding the iron mill scale to an effective particle size, which is 300μm. Latter, the grounded iron mill scale will undergo the magnetic separation process. The purpose of this process is to remove any non-magnetic material. Than the following process is to fully oxidize and reduce the iron mill scale to form pure iron powder. From this step an optimum value for maximum heating temperature, heating rate and heating cycle was determined. Than in order to determine whether the oxidation and the reduction process have completely achieved their objective, the iron oxide and the iron powder that have been produced from both process, was characterized using X-Ray Diffraction Analysis (XRD) and X-Ray Florescent Analysis (XRF) technique. From the oxidation process, it is obvious that sample C gave higher oxidation percentage, which is 11.22%. While Reduction 2 shows the desirable result, which is 29.51% of reduction, involving a low cost compared to other reduction process.

Oil Palm Ash is one of the abundance agricultural wastes found in Malaysia. This wastes need to be disposed properly. Oil palm ash contains compounds needed to produce glass. Most of raw materials (especially silica) used to produce existing commercial glass are imported; therefore it is the best time to highlight the potential of local natural waste as the raw material in glass production. In this study, raw material characterization, glass production and glass product evaluation has been done. A few parameters have been recognized to have effect on green glass production such as mixing compositions and firing temperature. Oil palm ash has been washed and dried then sieved to get uniformity of particle size. Then, oil palm ash is mixed with other glass materials such as alumina and flux and undergone melting process at 14000C. Through the experiments, the best glass compositions are as follows: 80% palm ash, 10% kaolin and 10% feldspar or 10% dolomite while the suitable temperature being used for sintering process to produced end product is range between 1150°C to 1200°.
