The elastic modulus of Ni-Ti alloys, which are with the pseudo elasticity, has been investigated by means of static tension method and nano-indentation method.
Principle, method and apparatus for young's modulus measurement of metallic material by indentation method are reviewed, and the methods error is analysed.
Scratch and indentation methods, which belong to a semi-static load method are used widely at present.
