Impact energy analysis of HSLA specimens after simulated welding thermal cycle

[摘要] This paper presents impact energy results of specimens made from high strength fine grained steel TStE 420 after thermal cycle simulation. These results are obtained by examining Charpy specimens. Metallographic analysis is performed,...
