Abstract

Abstract: The mechanical properties and fracture mode of disordered and ordered (Fe, Ni)₃V alloys with different boron contents in vacuum at the ambient temperature are studied. The results show that the grain size decreases continuously, and tensile strength and elongation increase with the increase of the boron content in the disordered and ordered (Fe, Ni)₃V alloys. The effect of boron content on the mechanical properties of the ordered (Fe, Ni)₃V alloy is significantly larger than that of the disordered (Fe, Ni)₃V alloy. It is deduced by the fracture surface morphology varying with the boron content in the ordered (Fe, Ni)₃V alloy that the change of the fracture mode is attributed to the segregation of boron on the grain boundary, thereby increasing strength of the grain boundary. Increases of the mechanical properties of the disordered (Fe, Ni)₃V alloy come from the effect of the grain size decrease. The increases of the mechanical properties of the ordered (Fe, Ni)₃V alloy are attributed to the joint effect of ordered strengthening, decreasing the grain size and improving the property of the grain boundary by boron atom.

Key words: (Fe, Ni)₃V alloy, boron, disordered state, mechanical property, ordered state
