Stress-Corrosion Cracking Property of Aluminum-Magnesium Alloy Processed by Equal-Channel Angular Pressing

Autor: Hiroaki Nakano, Satoshi Oue, Seiji Taguchi, Shigeo Kobayashi, Zenji Horita

Publikováno v: International Journal of Corrosion, Vol 2012 (2012)

Stress-corrosion cracking property of an aluminum-magnesium alloy processed by equal-channel angular pressing (ECAP) was investigated by a slow strain-rate tensile technique in a 3% NaCl solution of pH 4.2 at 303 K. The maximum stress and elongation
