.... Some types of AHSS have a higher strain-hardening capacity resulting in a strength-ductility balance superior to conventional steels. Many AHSS were developed for weight reduction, where the higher strength allows downgaging while maintaining sufficient formability to make a successful stamping...

The load-deformation relationship in the plastic region is nonlinear, as a result of phenomena such as strain hardening and area reduction. To understand all these fundamental issues, it is convenient to understand...

However, the cut edge of some steels becomes hardened during gas cutting, thus making subsequent processing difficult. Separation...
