| Description
| - Předložený článek pojednává o vlivu rychlosti ochlazování na hodnoty teplot fázových transformací niklové superslitiny IN 738LC. Zvláště se zaměřuje na stanovení teplot fázových transformací v průběhu tuhnutí a chladnutí a na vliv měnící se rychlosti ochlazování na tyto teploty. Vzorky odebrané z původního (litého) stavu superslitiny byly roztaveny řízenou rychlostí ohřevu (1, 5, 10 a 20°C/min) a ihned po roztavení byly řízeně ochlazovány stejnou rychlostí. K analýzám byl použit laboratorní systém fy SETARAM ? SETSYS 18TM TG/DTA/TMA. Pro studium této slitiny byla vybrána metoda diferenční termické analýzy (DTA). Protože rychlost ochlazování má také vliv na výslednou strukturní a chemickou (mikro)heterogenitu byly následně také mikroanalyticky studovány minoritní fáze v jednotlivých vzorcích pomocí elektronové mikrosondy a mikrostruktura jednotlivých vzorků byla dokumentována pomocí řádkovacího elektronového mikroskopu.

- The paper deals with the effect of cooling rate on the values of transformation temperatures of IN 738LC nickel based superalloy. Particular attention was given to the determination of phase transformation temperatures in the course of solidification and cooling and to the effect of varying cooling rate on these temperatures. Samples taken from as-received state of superalloy were heated with controlled ramp rates (1, 5, 10 and 20°C/min) and immediately after melting they were cooled with the same controlled ramp rate with the help of the laboratory experimental system SETARAM SETSYS 18TM TG/DTA/TMA. The technique of Differential Thermal Analysis (DTA) was selected for the detailed study of nickel based superalloys. Then the microanalysis of minority phases was conducted with use of X-ray spectroscopy and microstructure of the individual samples was documented by scanning electron microscopy.
