WebABSTRACT. The heat-affected zones (HAZ) of high strength steel weldments are a major concern to fabricators and operators because of the risk of fracture initiation from this area, particularly the coarse-grained HAZ. In recent years, titanium-alloyed steels have been developed which restrict grain growth in the HAZ and they exhibit improved ... WebThe zone shape and size is just the results of predicted temperatures and need to know the interface temperatures through phase diagrams, to be precise.

Web1 de mar. de 2024 · Calculations and experiments indicate that the thickness of the heat-affected zone produced by laser heating is close to the depth of material removal. When the pulse width is reduced to 10 μs, the heat-affected zone can be effectively limited. The Raman spectrum of the processing area also further verify this conclusion. Web29 de mar. de 2024 · Heat affected zones can be of varying size and strength. The extent and magnitude of the HAZ is inversely proportional to the thermal diffusivity and cooling rates of the material: Where thermal diffusivity is high, the material cooling rate is high and the HAZ is small.
