Crystallization of ductile iron melt - growth and heterogenity of graphitic cells
Stránský, K. ; Šenberger, J. ; Hoch, V. ; Kavička, F. ; Million, Bořivoj
Rate of transformation of melt-grafite heterogeneity of alloing elements C, Si, Mn, S, Mg and O in graphitic cells were calculated by means of model of growth of the spherical graphite particle with the austenitic cover from the ductile iron.
The problems of rating and of temperature influence on interaction coefficients in iron and steels
Stránský, Karel ; Kučera, Jaroslav ; Million, Bořivoj ; Šenberger, J.
The present paper deals with rating and with influence of temperature dependence of thermodynamic .epsilon.ic and diffusion .beta.ic interaction coefficients in .gamma.Fe and in austenitic steels. The investigation of the published and of our own data sets has shown that, in the frame of standard experimental deviations, the relation .beta.ic = .epsilon.ic.
Carbon and phosphorus redistribution in welded joints of carbon steels CSN(412050+0.1
Million, Bořivoj ; Stránský, K. ; Michalička, Petr ; Foret, R. ; Rek, A.
The diffusion specimens were isothermally annealed in the temperature range of 500 to 1100řC intervals. The concentration of P, C, Cr and Ni were measured by applying X-ray energy dispersion anlysis. The diffusion coefficients of P, C, Cr and Ni and thermodynamic interaction parameters were calculated. The uphill diffusion of phosphorus was observed on welding interface.
