Crack on Small Galvanneal Samples


2001

I have been conducting the annealing (air cooling) of hot dip galvanized steel plate (1mm thick) then I found cracks all over the surface perpendicular to steel base.

My hypothesis were:

1. the air cooling rate was too high or;

2. the sample was too small
