W artykule omówiono mechanizm pękania stopów w zakresie temperatur krzepnięcia. Przedstawiono hipotezę, że zjawisko to jest szczególnym przypadkiem tworzenia się kruchych pęknięć w metalach będących w kontakcie z cieczą (LME). Potwierdzono to doświadczalnie, badając właściwości mechaniczne stali w zakresie temperatur krzepnięcia. Stwierdzono, że charakter zniszczenia próbki zależy od szybkości deformacji...
The surface tension of Cd-Zn-Sn alloys with atomic ratio of zinc to tin equal to 0.25 and varied cadmium content determined by the maximum bubble pressure is presented. A model predicting the surface tension of multicomponent solutions from the knowledge of thermodynamic properties, densities and surface tensions for limiting binary mixtures has been implemented. A fairly good agreement between predicted...
