Hardness and microstructure of interstitial free steels in the early stage of high-pressure torsion
The hardness and microstructure distributions in interstitial free (IF) steel disks processed via the high-pressure torsion (HPT) process with an early stage (up to 1 turn) are investigated using experimental ...
