The present paper encompasses the fabrication, experimentation, testing and thermal property evaluation of LM25-Borosilicate glass (p) composites obtained through stir casting route with judicious selection and placement of different end chills within the sand molds. The composites required for the present study were cast by melting LM25 aluminum alloy into which varied weight percent of Borosilicate glass powder was introduced under the application of a mechanical stirrer. The melt with required content of reinforcement was introduced in a sand mold containing one end chill. Metallic end chills (copper and mild steel) and non- metallic end chills (silicon carbide and graphite) were employed in the current research. Various thermal tests were conducted on the specimens drawn from near the chill end to evaluate thermal diffusivity and thermal conductivity of the fabricated composite. The analysis of the obtained results illustrate the fact that end chill materials have a pronounced effect on the evaluated thermal properties of the composite as employment of metallic end chills resulted in the reduction of the thermal conductivity of the specimens as opposed with the thermal conductivity values for specimens fabricated with the aid of non-metallic end chills.
