13. Avaliação da tenacidade à fratura de soldas de alta resistência e baixa liga pelo método da integral-J. / Evaluation of high strength low alloy steel weld metal fracture toughness using the J-integral method.
The influence of the microstructure on the fracture toughness behaviour of two groups of multipass High Strength Low Alloy (HSLA) steel weld metals, presenting different microstructure composition, was evaluated. The weld metals A1/A2 exhibited a microstructure composed by acicular ferrite, allotriomorphic ferrite, Widmanstätten ferrite and microphases, and
