ABSTRACTThe fabricating conditions for the in-situ Al-Si base composite by the centrifugal casting method (CCM) have been examined. The crystallized Si particles with a lower density distribute in a gradient fashion as densely on the inner and thinly on the outer side of the wall of the cylindrical CCM-composite. Synthetically, the 25 mol% Si composite is recommended for the application like the engine liner.

TiN/Al2O3 functionally graded composite was fabricated by in-situ aluminothermic reduction of TiO2 in coke bed from mixtures of TiO2 powder and metal Al powder. The reaction process, phase composition, and microstructure of sample treated at 1500°C for 3h were analyzed by XRD, SEM and EPMA. The results indicated that the thermite reduction of TiO2 involves several transitional stages and its initial reaction temperature is lowered by prior reaction between Al and TiO2. EPMA analysis showed that the TiN/Al2O3 ratio in TiN/Al2O3 functionally graded material products changes gradually across the samples without distinct interface between the different layers. The microstructure of the composite changes gradually, and the size of TiN grains increases from the verge region of samples to the centre of samples. These results above were in agreement with thermodynamic analysis.

Ti/Al/TiC mixed powders were used as the raw materials for the fabrication of functionally graded material (FGM) in situ synthesis by spark plasma sintering. The sample was analyzed by SEM combined with Metallographic microscope and Energy Disperse Spectroscopy. The results show that dense Ti2AlC/TiC functionally graded material (FGM) was produced by spark plasma sintering. Micro-hardness tester is used to character the distribution of hardness on the material .The results show that the Vickers hardness of every layer increases with TiC content and temperature increasing.
