I used friction stir processing to reinforce aluminum alloy with nanoparticles and I want to calculate the weight fraction of reinforcement material.
Syed Khaja Naimuddin
Volume fraction = (Cross sectional area of the groove/Cross sectional area of the stir zone) * 100
Cross sectional area of the groove = (Width x Depth) for square or rectangular grooves
Cross sectional area of the groove = (Width x Depth) /2 for V shaped grooves
It is assumed that the particles are packed to full density in the groove.
once you know the volume, the weight can be calculated.
when the volume fraction is known you can know amount of reinforcement material by weight or volume.
