文摘

Structural and thermal sensitivity of Cu(60?em class="a-plus-plus">x)sub>Zr(30+x)sub>Ti10sub> (x=0, 5, and 10 at%) amorphous alloys to the application of tension was investigated. The structural sensitivity to tension decreases with increasing Cu content. The crystallization enthalpy increases with increasing excess free volume. The characteristic temperatures of the tensile samples can surpass those of the as-cast ones under a critical heating rate which differs in the Cu content. The increase of the excess free volume significantly influences the glass transition and crystallization procedures.
