摘要：

The　microstructure　and　indentation　behavior　of　Ag/Co,　Ag/Cu,　Ag/Ni,　Cu/W　and　Ni/Ru　multilayers　were　investigated.　The　results　indicate　that　the　deformation　characteristic　is　influenced　by　grain　morphology.　The　Ag/Co　and　Ag/Cu　with　equi-axed　grains　deform　by　shear　bands,　while　the　Ag/Ni　and　Cu/W　with　compressed　grains　deform　homogenously.　This　difference　is　interpreted　by　cooperative　grain　boundary　sliding　which　can　occur　only　in　equi-axed　grain　materials.　For　Ni/Ru　multilayer,　the　shear　bands　may　occurs　by　shear　sliding　of　adjacent　columns.　(C)　2009　Elsevier　B.V.　All　rights　reserved.
