THE DISCUSSION ON THE FORMULA OF STRAIN HARDENING EXPONENT (n-VALUES)
According to the standard of metallic materials-sheet and strip-determination of tensile strain hardening exponent (n-values)(GB/T5028-1999), the data analysis is very complex and easy to make mistakes. Compare to Five point method, Two point method is convenient and accurate in the day-to-day test, the error between them is less than 0.5 percent, the work efficiency improves quickly.
