Paper Title:
In Situ AFM Observation of Mechanical Behavior of Beta Titanium Alloy in Nano-Indentation Test
  Abstract

In this study, depth sensing nano-indntation test combined with in-situ atom force microscope (AFM) is carried out to investigate the plastic/viscoplastic behavior of beta titanium alloy. The indentation experiment results show that with the increasing nominal indentation strain rate, the hardening effect becomes stronger in the loading part, while the creep induced softening behavior becomes stronger in the unloading part. The residual penetration depth is deeper when the indentation strain rate increases. A new quantity named nominal hardness/modulus ratio is defined to characterize the plastic behavior of beta titanium at micro region.
