REVIEW ON EFFECT OF VARIOUS REINFORCEMENTS ON THE THERMAL PROPERTIES OF LM-25 AL ALLOY AND SOME COMMON LIGHT METAL ALLOYS

For thermal management in applications like automobiles, aviation, marine etc. we need materials with high thermal conductivity, low coefficient of thermal expansion and at the same time the materials should have high strength, high corrosion resistance and low density. Aluminum alloys are excellent choices as the alloys possess all these properties. In order to improve the properties of the alloys further to make them more suitable for the applications, alloys are reinforced with different materials. This review focuses on influence on thermal properties of LM25 and some common light metal alloys reinforced with different materials, effect of heat and solution treatments on LM25/SiC MMC, effect of aging treatment on thermal fatigue of LM-25 alloy and the most common synthesis technique used
