6. Closure: Resembling Michelangelo Stone Sculpture Texture (MSST) With regard to the HDT in the form of TTS in high-strength eutectoid pearlitic steels, cf. Fig. 1, in certain sense it could be associated with the Michelangelo Stone Sculpture Texture (MSST) shown in Fig. 2 for the Pietà di Firenze and the Pietá Rondanini .
