研究了电沉积的Pd-P和Pd-Ni-P玻璃膜的弯曲行为。从局域变形到非局域变形过渡的临界厚度取决于温度和应变速率，而屈服强度是否取决于尺寸。应变速率降低和温度升高引起的杨氏模量下降导致剪切带扩展应力的下降幅度小于剪切带成核应力的下降幅度，导致非局部变形的临界厚度增加。(C) 2012材料学报Elsevier Ltd.出版。版权所有。
The bending behavior of electrodeposited Pd-P and Pd-Ni-P glassy films was investigated. The critical thickness for the transition from localized to non-localized deformation depends on temperature and strain rate, whether the yield strength is size dependent or not. The drop in Young's modulus induced by the decreased strain rate and increased temperature results in a smaller decrease in the stress for shear band propagation in comparison with the stress for shear band nucleation, leading to an increased critical thickness for non-localized deformation.
