Heat affected zone in surfacing chromium ledeburitic steel [PDF]

open access: yesMetalurgija, 2010
Tools get failured during work; wear is a major factor that contributes to failures. Damaged tools are replaced or filed. This paper describes typical changes that occur in the heat affected zone of tool (HAZ), which was repaired by surfacing with a TIG ...
