LCA is a process of evaluating the environmental impacts associated with a product, process, or activity by: identifying and quantifying the energy and materials used and the wastes released to the environment; assessing the impacts of those energy and material uses and releases to the environment; and identifying and evaluating opportunities for environmental improvements [9].
All emissions, energy consumption, materials and cost are based on this functional unit.

Hence, the reaction of hard materials to shock loading is essential for alleviating shock-induced failures and damages.
Hence, the continuous impact of loading materials on the surface of the hammer tends to cause chemical-erosion [23].

Introduction Nowadays materials are tailor made for particular applications inorder to meet specific design criteria (El Baradie (1)).
In MMCs Aluminium and its alloys are the most frequently used matrix materials due to their low density and moderate strength.
