| Abstract |
| The mechanical properties and corrosion behavior in welded EH36 TMCP steel were investigated with different Ni content and heat input. Weldments were produced by adjusting the heat input and Ni content of 0, 1.3 wt%. The acicular ferrite fraction increased as the Ni content increased. In contrast, the grainboundary ferrite and Widmanstatten ferrite decreased. The impact energy absorption increased with the addition of the Ni content and decreased as the test temperature decreased. Both tensile and yield strengths increased with either the addition of Ni or reduced heat input. As a result of the polarisation test conducted in a salt solution, the corrosion potential of the 1.3 wt% Ni added specimens was higher than the free Ni specimens. |
