Investigation of fracture in Fe3Al-based alloys with vanadium and carbon additions by small punch test
Original language description
Creep resistance of iron-aluminium-based can be improved by introducing second-phase particles, e. g., by additions of carbon and carbide-forming elements. The presence of carbides may negatively influence the ductility of alloys. In the present study, the effect of vanadium and carbon additions on ductility of Fe3Al-type alloy was investigated. The constant-deflection-rate mode of the small punch test was used to compare fracture properties and their temperature dependence in the alloys with differentamounts of carbon. Three main quantities were evaluated: maximum force, fracture deflection and fracture energy. Fractographic observations of ruptured specimens were performed with scanning electron microscope. Temperature dependence of small punch testquantities was related to the microscopic image of the fracture. Equivalent fracture strain was evaluated from both small punch test data and microscopic observation of fractured specimens. The relation between equivalent fracture strain
