Al-B4C composites. Attempts were made to overcome the wetting problem between B4C and liquid aluminium at lower temperatures for promising the mechanical and tribological behaviour of the Al -B4C composites. AA6061-B4C particle reinforced composites were produced through casting route at 850ºC with K2TiF6 added as flux to overcome the wetting problem between B4C and liquid aluminium metal. The Aluminium B4C composite samples were subsequently subjected to T6 heat treatment. The composite samples

behavior of Brass‚ Copper‚ Aluminium. A series of experiments involving cold rolling (58% cold work) have been conducted for those three materials. The Vickers number of hardness for cold rolled specimens can be show very clearly that it has increasing up the number itself likewise the number of thickness reduction which also increasing. Which its number of Vickers can be rated as follow as Aluminium < Copper < Brass ; this means that Brass has the most tensile strength‚ Aluminium is easily to bend and
