The results show that for both the aged conditions, creep age under stress of 200 MPa leads to the uneven distribution of S......
the mechanical properties, i.e. modulus of elasticity and creep strain rate sensitivity by using depth-sensing micro-indentation with the influence of loading rates on load-displacement (F-h) relationship. The resulting indentation F-h curves are loading-rate-dependent and have varying creep penetration depths during the same hold time. The derived modulus of elasticity values with Oliver-Pharr......
