Abstract

Material properties were evaluated for the laser cladding of 410L grade stainless steel on a hypereutectoid steel rail substrate under two different heat treatment conditions. Miniature tensile test samples were produced to evaluate the mechanical properties of the clad layer and HAZ. The tensile properties, in particular ductility, were improved by a post-heating and slow cooling rate which resulted in a more favourable microstructure. Elongation values were increased by 423% and 186% for the clad layer and HAZ, respectively, compared to pre-heat treatment. The post-heat treatment also marginally increased the tensile strength in these regions.
