Dynamic　behavior　under　cyclic　loading　conditions　and　creep　behavior　under　quasi-static　loading　conditions　were　investigated　by　instrumented　indentation　of　pure　aluminum　to　reveal　the　influence　of　loading　conditions　(e.g.,　load,　loading　rate,　and　holding　time)　on　indentation　responses.　The　results　of　cyclic　indentation　show　that,　with　the　increase　in　the　holding　time,　load,　and　loading　rate　of　the　pre-cyclic　loading　segment,　the　effect　of　creep　on　the　subsequent　cyclic　indentation　can　be　weakened,　and　the　measured　mechanical　properties　(e.g.,　contact　depth,　indentation　hardness,　and　elastic　modulus)　can　reach　constant　levels　more　rapidly　with　the　increase　in　cycle　number.　The　results　of　the　creep　tests　show　that　the　elastic　modulus　and　indentation　hardness　decrease　with　the　increase　in　holding　time,　the　steady-state　creep　stress　exponent　obtained　by　instrumented　indentation　is　independent　of　load,　and　a　long　holding　time　is　not　suggested　for　the　creep　tests.　Indentation　hardness　and　steady-state　creep　resistance　measured　within　the　inner　grains　are　higher　than　those　measured　near　the　grain　boundary　regions.　©　2023　Chinese　Academy　of　Sciences.　All　rights　reserved.
