摘　　要：金属多层膜在高温低应力条件下发生弹性蠕变时,由于膜的塑性流动,使得测量金属固固相界面能成为可能。介绍了一种测量金属固-固相界面能的方法——零蠕变法,并着重阐述双向零蠕变法的原理和设备。Metal multilayers deform by elastic creep under the condition of high temperature and low stress. Metal solid-solid interfacial energies can be determined when plastic flow is possible in the multilayers.Therefore,a new method named Zero Creep Measurements has been introduced to measure the interfacial energies.The principle and devices for Biaxial Zero Creep Measurements are emphatically described.
