Right ventricular endomyocardial biopsy morphometric findings were correlated with those of full-thickness samples of the right ventricle and interventricular septum obtained from the hearts of the same patients at cardiac transplant. The percentage area of myocytes and fibrosis was measured on histologic sections by means of a quantitative method. The results showed a close correlation between fibrosis and myocytes of biopsies and those of subendocardial, subepicardial, and midwall layers of the right ventricle free wall. No correlation was found with the subendocardial layers or with the midwall of the interventricular septum. These data suggest that histologic features of biopsies taken from the right ventricle from patients with dilated cardiomyopathy resemble those of the right ventricle free wall only.

The glow discharge optical emission spectroscopy depth profiles reveal layering of the deposited material with a good correlation between the sequence of layers in the composition profile and that observed by transmission electron microscopy.

However, their aging at 600–1000 °C causes the precipitation of dangerous intermetallic phases, resulting in serious detrimental effects on their interesting properties. These secondary phases are structural discontinuities which act as preferential cracks initiation sites and their negative effect is especially highlighted on toughness. For these reasons, many standards related to the manufacturing of DSS require the microstructure of these steels "free from intermetallics". In this paper, the effect of isothermal heat treatments on the impact toughness in two Duplex steels (SAF 2205 and Zeron®100) has been investigated, in order to study the influence of different amount of secondary phases on the toughness response.
