. The effect of temperature on impact toughness was analyzed by the model and the trend of the simulation results was basicly consistent with the previous experimental results of CLAM steels. The load-displacement curve was simulated to express the low temperature ductile-brittle transition. The effect of grain size and inclusion was analyzed by the model, which was consistent with classical experiment results. The transgranular-intergranular transformation in brittle materials was also simulated. | Simulation of impact toughness with the effect of temperature and irradiation in steels Nuclear Engineering and Technology 51 (2019) 221e227 Contents lists available at ScienceDirect Nuclear Engineering and Technology journal homepage: Original Article Simulation of impact toughness with the effect of temperature and irradiation in steels Chenchong Wang a, Jinliang Wang a, Yuhao Li c, Chi Zhang b, Wei Xu a, * a State Key Laboratory of Rolling and Automation, School of Materials Science and Engineering, Northeastern University, Shenyang 110819, China b Key Laboratory of Advanced Materials of Ministry of Education, School of Materials Science and Engineering, Tsinghua University, Beijing 100084, China c High School Attached to Beijing University of Technology, Beijing 100022, China a r t i c l e i n f o a b s t r a c t Article history: One of the important requirements for the application of reduced activation ferritic/martensitic steel is to Received 26 February 2018 retain proper mechanical properties in irradiation and high temperature conditions.
