The Production Of Cast Metal Matrix Composite By A Modified Stir Casting Method [PDF]
In a normal practice of stir casting technique, cast metal matrix composites (MMC) is produced by melting the matrix material in a vessel, then the molten metal is stirred thoroughly to form a vortex and the reinforcement particles are introduced through

Correlation between micro-hardness and mineral content in healthy human enamel. [PDF]
Enamel is the hardest and the stiffest tissue in the human body. The enamel undergoes multidirectional stresses, withstands multimillion chewing cycles, all while protecting the internal dentin and pulp from damage due to mechanical overload and exposure to the harsh chemical environment of the mouth.

Micro-hardness of surface layer of irradiated polypropylene [PDF]
Using high doses of beta radiation for polypropylene (PP) and its influence on the changes of micromechanical properties of surface layer has not been studied in detail so far. The specimens of PP were made by injection moulding technology and irradiated by high doses of beta radiation (0, 33, and 66 kGy).
