Book Description
This research work involves macro and micro scale processing of Al-alloys. At micro level, pillars were generated from AL-Sn-Mg powders and binder mixture. Both conventional and current activated sintering processes were investigated in order to do sintering. Two types of binders and solvent system were investigated. Paraffin wax (PW) and n-heptane was used with AL-Sn-Mg powders and polyethylene glycol (PEG) and water was used with Al-SN powders. Setup was designed and fabricated to generate pillars and for DC current activated sintering. Rolling technique and very low pressure was applied in this application. At macro level, press and sinter technique was investigated to compare the mechanical properties such as density, hardness and shrinkage of mechanically alloyed Al-Sn-Mg powders and unmilled powders. The result shows that the MA powders have higher mechanical properties compared to unmilled powders. However, unmilled powder compact sintered very nicely and used for further processing. Green pillars were successfully generated using both binder systems. For sintering, conventional sintering appeared more successful than current activated sintering.
