[ 1 ] - Formation of Two Types of Alumina/Intermetallic Composites based on the Reaction of Ilmenite and Aluminum

Ilmenite is a valuable industrial mineral containing Fe and Ti elements. Two composites with different morphology and composition were produced using the reaction of synthesized ilmenite and aluminum. The molar ratios of 1:2 and 1:8 were selected. The critical temperatures of each molar ratio were determined using the Differential Thermal Analysis (DTA). The heat treatment of the systems ...

[ 2 ] - The Effect of Raw Material Ratios on the Fe-TiC/Al2O3 Composite Formation Mechanism

Ilmenite, aluminum and graphite can be used to produce in-situ Al2O3/TiC–Fe composites which are used as cutting tools. Few publications can be found in the literature that discusse the effect of molar ratio of aluminum and graphite on the Al2O3/TiC–Fe formation mechanism. Therefore, the present research is designed to make the issue clear. To achieve this goal, at first, the mechanism o...
