Figure 4
Comparison of melt pools computed by the models. The melt pools are projected onto planes perpendicular and parallel to the laser velocity. The contours are cooling rates \(\dot{T}\). The left column shows comparisons between the convective and conductive models for the optimal (\(\alpha\),\(z_S\)) pairs in Table 1 for the \({\hbox {SMG}}_3\) and \({\hbox {SG}}_3\) cases. The middle column shows a comparison between convective models with \((\alpha ,z_S)\) values at opposite extremes of the ranges for the \({\hbox {SMG}}_3\) and \({\hbox {SG}}_4\) cases. The right column shows a comparison between convective models with \((\alpha ,z_S)\) values at opposite extremes of the grayed regions for the \({\hbox {SG}}_3\) and \({\hbox {TG}}_2\) cases. In each case, the melt pool traces of the two melt pools are very close to the experimental results.
