Dr. SHEN Laiquan, Prof. BAI Haiyang, Prof. SUN Baoan, and others from Prof. WANG Weihua's group at the Institute of Physics of the Chinese Academy of Sciences (CAS) have successfully observed the effect of cavitation on fracture behavior in glasses. They revealed that crack propagation is dominated by the self-organized nucleation, growth, and coalescence of nanocavities in metallic glasses.
