The manufacture and investigation of abrasion resistant Fe-V-C alloys.

Abstract

This dissertation deals with alloys containing between 0.2 and 9.5wt%, carbon and between 3.2 and 64.3wt% vanadium with the balance iron. Alloys were produced by induction melting and followed by remelting in vacuum tungsten arc furnaces. No heat-treatment was performed, as the aim was to identify useful alloys that may be applied by hardfacing techniques in the field. The requirement of post weld heat-treatment would greatly limi~ the use af hardfacing alloys. TIle experimental techniques aimed at characterising the alloys included X-ray diffraction analyses, Mosshauer Spectroscopy, optical, scanning and transmission electron microscopy and chemical analyses white density measurements, hardness tests and 2 and 3 -body abrasion test gave the material properties.
