文摘A remarkable enhancement in room-temperature compressive deformability is realized by the minor-addition of 1.5 at.%Al in ZrTi-based bulk metallic glass.Two amorphous phases are observed by transmission electron microscopy in the Al-containing alloys and this explains the improvement of compression deformability.The studies suggest that phase separation might occur in glass forming alloys with a negative enthalpy of mixing.
