Impact Toughness of Heat-Affected Zones of 11Cr Heat-Resistant Steels [PDF]
Acta Metallurgica Sinica (English Letters), 2020 Aiming at the requirements of structural steel in Gen-IV nuclear reactor, the high-chromium martensitic heat-resistant steels containing 10–12% chromium were developed. The toughness of heat-affected zones (HAZs) is one of the important factors for evaluating the weldability of steels.
