摘要
Quick preheating treatment of Al-Ti-C was introduced in the fabrication of in situ TiC/Al metal matrix composites in our research. Al-Ti-C pellets were preheated in the furnace at 750 degrees C, in which the pure aluminum was melted. After adding the preheated pellets into the molten aluminum, the thermal explosion reaction of Al-Ti-C took place in a short time. In situ TiC particles synthesized in the pure molten aluminum were spherical in morphology and most of which were smaller than 1 mu m in size. The synthesizing temperature of in situ TiC/Al composites was decreased significantly by using the quick preheating treatment, at least 150 degrees C lower than those used in the conventional methods. In addition, high-intensity ultrasonic vibration was applied into the melt to disperse TiC particle-reinforcement into the matrix and degas the melt as well. In situ TiC particles were distributed uniformly in the matrix, and the porosity in the composites was below 1% due to the effect of ultrasonic vibration. Furthermore, the microhardness test indicated that a homogeneous microstructure of in situ TiC/Al composite was obtained. (C) 2011 Elsevier Ltd. All rights reserved.
