The Effect of Coat on the r Value of Galvanized Sheets
It is known that the r-value of steel sheets is decreased due to galvanizing.In the paper, the influences of galvanizing coat on r-value has been investigated by tensile test, SEM examination and theoretical analysis.The research shows that the transversal cracks in the coat is the main cause of decreasing r-value.
