2.Its microstructure include: dimple, plastic intererystalline, cleavage and mixed fracture.
3.The fracture surface is dimple fracture for Ni_(40)Ti_(50)Fe_(10) alloy tested in vacuum. The tensile ductility of specimen decreases with the decreasing strain rate in air. The fracture surface tested in air shows a mixed mode of dimple fracture and cleavage patterns.
4.FZN25 and FZRN25 series can realize one off operation of isolation clearance and are extinguishing chamber clearance.
5.The toughness experiments indicate that the fracture of macro-structure of the austenite-bainite ductile cast iron is of brittle fracture, while the fracture of micro-structure is of mainly ductile fracture with dimple appearance.
6.The fracture appearances transfer from dimple to intercrystalline fracture with the temperature drops and cleavage fracture appear when work hardening happened.
7.The fracture appearance is dimple at room temperature,it changes into intercrystalline fracture at low-temperature.
8.The raw hot rolling stick has plastic dimple fracture surface and aging-treated specimens have plastic and brittle mixed fracture surface but brittle is main.
