All you need to know about the heat-affected zone

The most important factor that influences the creation of the HAZ is thermal diffusivity. Technically speaking, this coefficient depends on thermal conductivity, density, and specific heat of a substance. Materials that show a high thermal diffusivity are able to quickly transfer variations in heat, rather than heat itself. In other words, if a material demonstrates high thermal diffusivity, it cools faster, and HAZ is reduced.
