	Long-time oxidation of carbon steel grade 55 and bearing steel LH15 at high temperatuers Adamaszek, K. ; Jurasz, Z. ; Kučera, Jaroslav High temperature oxidation of the cylindrical samples (f = 10 diameter and l = 15mm length) made of carbon steel grade 55 and bearing steel LH15 has been performed in air in temperature range 940ů1100°C and for various times. Using the experimentally measured thickness of scale layers, the oxidation process of mentioned steels have been compared. Detailed record
	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. Detailed record
	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. Detailed record
	The measurement of carbon diffusion in steels by chromatografic method Hajduga, M. ; Kučera, Jaroslav Detailed record
	Decarburization and Microhardness Changes of Fe-C-Cr Steels during High-Temperature Oxidation in Air Hajduga, M. ; Glowacki, J. ; Kučera, Jaroslav ; Brož, P. Detailed record
	Diffusion of carbon and changes of hardness of steels Fe-C-Cr caused by high temperature oxidation on air Kučera, Jaroslav ; Hajduga, M. ; Glowacki, J. ; Brož, P. Detailed record
	Redistribuce uhlíku a dusíku ve svarech ocelí Stránský, Karel ; Million, Bořivoj ; Rek, A. ; Michalička, Petr ; Pilous, V. ; Kučera, Jaroslav Detailed record
	Difúze dusíku ve svarech typu (Fe/N)/(ČSN 417241) Kučera, Jaroslav ; Macoszek, M. ; Million, Bořivoj ; Rek, A. ; Pilous, V. ; Stránský, K. Detailed record
	Gravimetrické a metalografické studium vysokoteplotní oxidace Fe-součástek válečkového tvaru Hajduga, M. ; Kučera, Jaroslav Detailed record
	Závislost oxidace válcovitých vzorků železa na čase; při teplotě 1100.DEG.C Kučera, Jaroslav ; Hajduga, M. Detailed record
