Abstract
This study discusses the effect of Ni content of low-transformation-temperature (LTT) fillers on welding residual stresses of AISI 410 plates. The plates were joined by LTT fillers with 11 wt-% Cr and varying Ni from 3 to 11 wt-%. Evaluation of varying Ni content on the martensitic transformation temperature (M s) by dilatometric tests indicates that the M s of LTT fillers decreases from 335°C to 67°C by increasing Ni wt-%. Residual stress measurements show the highest compressive longitudinal stress (−310 MPa) in the weld bead deposited by the LTT filler contained 7 wt-% Ni and M s= 202°C. This result is associated with the highest final expansion strain (0.37%) in this composition. Microstructural analyses show the presence of retained austenite by increasing the Ni more than 7 wt-%.
