摘要:

    新型功能材料及器件向小型化，集成化和復合化發展的趨勢，使得尺寸在納米尺度的層狀材料和柔性多層器件在使用過程中的服役行為成為其發展的關鍵科學問題。本文結合作者近幾年對Ag/M系列和Cu/M系列多層膜力學性能的研究工作，對金屬納米多層膜的微結構特征及其對力學性能的影響進行了回顧和總結，主要包括多層膜的晶粒形貌對其強化機制和塑性變形行為的影響，組元強度錯配對多層膜硬化行為的影響，界面結構與其強度極值的關系、不對稱界面結構引起的異常彈性模量增強和多層膜的室溫蠕變機制及界面結構對蠕變性能的影響等幾個方面,并對多層膜的力學性能研究進行了展望。

Abstract:

    The tendency of new functional materials and devices to being miniature, integrated and laminated makes the mechanical behavior of those materials in nano scale a key scientific issue for the development of the multilayers and devices. Recent researches and developments on the mechanical properties of nanoscale metallic multilayers were summarized and introduced in this article based on our own works on Ag/ M and Cu/ M multilayers，including issues related to the influence of grain morphology on strengthening mechanisms and plastic deformation behavior...
