Nanoindentation technique was adopted to study indentation size effects of physical-mechanical and creep performance with various depths (200-2000 nm) in GH901 utilising sharp and spherical tip. Residual impressions of both indenters with pile-up patterns are discussed. Nanohardness, reduced modulus...
