The frequency of heterogeneous nucleation during the solidification of Al-Si binary alloy was estimated by comparing ex-perimentally obtained macrostructures of
A genetic algorithm based on the nested intervals chaos search (NICGA) has been given. Because the nested intervalschaos search is introduced into the NICGA to
Independent microstructures made of Ni metal were fabricated by five sequential processes: porous anodic oxide film for-mation, pore sealing, laser irradiation,
Based on the electric-spark principle, a new kind of cavitation damage testing apparatus was designed, which could produce the bubble. Bubbles collapsed and act
