摘要：

For　the　problem　that　the　value　of　test　force　will　influence　the　result　of　instrumented　indentation　hardness　test,　the　relation　between　test　force　and　instrumented　indentation　hardness,　indentation　modulus　were　investigated.　55　groups　of　tests　were　carried　out,　in　which　the　test　force　were　divided　to　11　different　levels.　On　the　basis　of　110　test　data,　differences　were　analyzed　and　the　relation　curves　were　plotted　by　Origin.　And　the　relative　difference　value　was　proposed.　Results　show　that　when　19.　61N≤Fmax≤98.　07N,　the　change　of　test　force　makes　little　influence　on　instrumented　indentation　test　(IIT)　results　and　coefficient　of　variation(CV);　when　0.　98N≤Fmax≤9.　81N　or　196.　14N≤Fmax≤294.　21N,　the　change　of　test　force　makes　remarkable　influence　on　IIT　results　and　CV.　©　(2014)　Trans　Tech　Publications,　Switzerland.
