Influence of the load on nanoindentation behavior of Gum metal

It is possible to get the various special properties by adding alloying elements to titanium. Gum Metal is a titanium base alloy developed to achieve low Young’s modulus similar to cortical bones. When the alloy is cold worked, it shows the special mechanical and physical properties different from ordinary metallic materials. It has been thought that this phenomenon is related to unique deformation mechanism of Gum Metal. In the present study, influence of the loading conditions on mechanical response during nanoindentation was investigated for the purpose of analyzing the unique deformation mechanism.
