Processed Data_Local fracture criterion H-assisted quasi-cleavage cracking tempered martensitic steels

Analysis of the data to evaluate hydrogen-assisted cracking of three tempered martensitic steels (Ref -0.3C0.2Si0.4Mn1.0Cr_0.8Mo, HMV-0.3C0.3Si0.3Mn0.5Cr-1.8Mo-0.2V, HCV-0.6C0.3Si0.3Mn1.0Cr1.2Mo0.15V). It comprises:

- Summary_Fracture-Criterion:
Fracture conditions (stresses, plastic strain, hydrogen concentration and flux) from the FEM calculations performed as described in the paper linked to this dataset.

-Summary_Tensile-testing:
Summary of the main experimental mechanical and hydrogen charging parameters for tensile tests with unnotched and notched specimens without hydrogen, after hydrogen pre-charging and desorption and under electrochemical permeation hydrogen flux.

-Summary_KI-Calculation:
Summary of the stress intensity factors (KI) reached for shifting from quasi-cleavage cracking to ductile fracture propagation for tensile tests with notched specimens under electrochemical permeation hydrogen flux.
