(a) (b) Fig. 5 Micromechanism of HAC: (a) hydrogen diffusion in longitudinal and transverse directions, (b) fracture by hydrogen enhanced delamination or debonding (HEDE). 6. Closure: A Tribute to Andrea Mantegna Heavily cold-drawn pearlitic steels exhibit in their HACP evidence of strongly anisotropic behavior with a marked deflection/deviation angle of 90º. This resembles Mantegna’s Dead Christ Perspective (MDCP) painting with is relevant and innovative change of point of view in the description of the Dead Christ (90º rotated from the traditional perspectives) with his body axis perpendicular to the canvas ( foreshortening perspective ), see Fig. 6.
