Notes:
The tensile tests and the three-point bending tests have been conducted to investigate thecrack initiation and propagation and the fracture behavior of 91W-6.3Ni-2.7Fe with three kindsgrain sizes of 1~3μm, 10~15μm and 30~40μm. SEM was introduced to analyze the grain sizes, themicro-defects, the deformations and the fracture behaviors of tungsten alloys. The test results showthat under the same loading conditions, the crack initiation and the crack propagation are not onlyrelated to grain size, but also related to the contiguity of tungsten grains and the interface between thetungsten grains and the matrix
