Heat affected zone in surfacing chromium ledeburitic steel [PDF]
Metalurgija, 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 ...

On the Brittleness of Heat-Affected Zone (Report 9)
Journal of the Japan Welding Society, 1956 Distribution of the toughness in the neighbour of weld, depending on the hysteresis and the directionality of the steel plate, are examined. Usability of the "Synthetic Impact Test Specimens" are considered. Max. brittle ratio of the heat-affected zone of the full-annealed steel plate seems to be greater than that of as-rolled steel plate.

Study on the Corrosion Behavior of 7A52 Al Alloy Welded Joint by Electrochemical Method
International Journal of Electrochemical Science, 2013 Twin-wire metal inert gas arc welding (TMW) was used to join the 7A52 Al alloy plates with the ER 5356 filler. The microstructure observation showed that the joint included four zones, i. e., base metal, heat affected zone, fusion zone and weld zone. The
