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.
Decarburization of Fe-C-Cr-Mn-Si steels at high temperatures in ambient air
Hajduga, M. ; Glowacki, J. ; Kučera, Jaroslav
The measured values of carbon concentration N(C,x,t) make it possible to get the diffusivities D(C) and hardness values HV(x,t) the coefficients D(HV). The values D(HV)=D(C) in the case that HV(x,t) values are dierectly proportional to N(C,x,t). It is shown that the fatigue limit of carbon steels may calculated from the relation ńëa=0.235HV05.
