Deep Cryogenic Treatment on Aluminum Silicon Carbide (Al-SiC) Composite
Deep cryogenic treatment produces a significant enhancement in the mechanical properties of metals. In this research paper, the mechanical properties of Aluminium Silicon composite were studied when they were subjected to deep cryogenic treatment. Samples were prepared from two different compositions of Aluminum silicon composites (Al 2024_5%SiC & 10%SiC). The samples were given controlled cryogenic treatment at -186oC. Treated samples were compared with un-treated samples for their compressive strength, hardness and metallurgical changes. The treated samples have shown an improved compressive strength. The improvement is supplemented by the hardness survey and micro-structural changes.
