Dissertation submitted to the faculty of Engineeung, University if the Witwatersrand,
Johannesburg. in fulfilment of the requirements for the degree of Master of Science in
Engineering. / 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. (Abbreviation abstract) / AC 2018
