Abstract

The Zr56Co22Al16Ag6 bulk metallic glass composite with nanocrystal precipitation couold be formed in situ in a large cooling-rate range. The authors reported the nanoscale corrugations on the compressive fracture surface of Zr56Co22Al 16Ag6 bulk metallic glass composite with in situ precipitated nanocrystalloids. The results confirmed that the formation of the nanoscale corrugation followed the plastic flow, microbranching trigger, microvoids growth/coalescence mechanism. Between the main corrugations some tiny corrugations were observed to be perpendicular to the main ones. The corrugations with different directions traveled forward along their own direction, then crossed each other, but did not change their propagating directions.
