ABSTRACT: Models have been derived for assessment and computational analysis of the hardness of the
heat affected zone (HAZ) in aluminum weldment. The general model;
γ = 1.2714[(αβ/α + β)]
was found to predict the HAZ hardness of aluminum weldment cooled in water as a function
of the HAZ hardness of both mild steel and cast iron welded and cooled under the same
conditions. The maximum deviations of the model-predicted HAZ hardness values γ, α and β
from the corresponding experimental values γexp, αexp and βexp were less than 0.02%
respectively.
