Measurements and determinations of matrix micro-properties in tungsten alloy
The average micro-hardness and average micro-elastic-modulus of matrix in tungsten alloy were respectively determined by nano-indentation tests and the statistic principle was proposed in mis paper. Using the finite element method and the hardening model of materials with load-displacement relationships obtained from nano-indentation tests, the parameters of the micro-yield strength and hardening modulus of matrix in the tungsten alloy were given. Therefore the elastic-plastic properties of the matrix in tungsten alloy were obtained and it provided the basis for studying the relationships of macro-mechanical behavior with the micro-structures of tungsten alloy.
