An experimental design was developed to show the effect of the amount of the various alloying elements (Sn, Bi, Pb) on this phenomenon. The characterization of the effect was obtained by 1) deformation by three-point bending of a piece of steel with different levels of deflection;2) galvanizing and 3) observation and measurement of the cracks. A model of the critical deflection (deflection for crack starting) with the amounts of Sn, Pb, and Bi is presented and the predictions are described.展开更多
