Web21 de sept. de 2024 · The toughness of a weld joint often deteriorates in the vicinity of the coarse-grained heat affected zone (CG HAZ), where the prior austenite grain size is the largest. For this reason, many CCT diagrams for welding have been developed for the CG HAZ, where the maximum temperature is between 1350°C and 1400°C. WebThe heat affected zone (HAZ) is the area adjacent to the weld that was heated high enough to affect its microstructure but not enough to melt it. By undergoing microstructural changes the HAZ has different …
