“…The experimental results revealed that the location and orientation of pores and metallic insertions had significant effects. Additional energy losses at the contact surfaces of inclusions resulted in higher electrical resistivity of samples with inclusions, compared to predictions based on formula (2).…”

A rotational, contactless inductive measurement technique has been used to determine the effect of pores and metallic insertions on the electrical resistivity of A2011 aluminium alloy at different temperatures. It is shown that the electrical resistivity increases with the total volume of pores, and is also dependent on the location and orientation of pores. Additional energy losses were found on the contact surfaces between sample and insertions.MST/5933

“…During the viscosity measurements, a torsion force acts on the crucible, which results in the crucible rotates and brings shear force on the surface of the samples. That shear force is transmitted through the stored potential energy of the lattice to act on each individual molecule and arouses the molecular rearrangement [29]. Subsequently, a viscous flow forms, and then dissipates that stored potential energy.…”
