Effects on hardness and microstructure of AISI 1020 low-carbon steel processed by high-pressure torsion

Diana Maritza Marulanda Cardona, Jittraporn Wongsa‐Ngam, Hernando Jiménez, Terence G. Langdon

Low-carbon steel AISI 1020 was subjected to high-pressure torsion (HPT) with 6.0 GPa pressure through 1/4–5 turns. The microstructures of the samples in each turn were studied by means of X-ray diffraction (XRD) analyzing the changes in micro-strain, crystallite size and lattice …
