Stability of eutectic carbide in Fe-Cr-Mo-W-V-C alloy
The stability of the eutectic carbide in a self-designed Fe-Cr-Mo-W-V-C alloy during solidifi atio as a alyzed i this ork. The ar ide pre ipitatio rule of the steel was calculated by Thermo-Calc.The typical microstructures at 1240 °C and 1200 °C ere o ser ed y opti al i ros ope OM ,field e issio s a i g ele tro microscope (FESEM) and transmission electron microscope (TEM). The selected area dif...
متن کاملMechanism of Bainite Transformation in Fe-Cr-Mo-V-Ti-C Steel
The kinetics and mechanism of bainite transformation have been studied in Fe-Cr-Mo-V-Ti-C steel high speed dilatometry backed by thermodynamic analysis. The complete transformation of austenite, however, has not occurred at any reported temperature. Obtained results confirm the incomplete reaction phenomenon with the cessation of the bainite transformation well before the paraequilibrium is ach...
متن کاملGrowth characteristics of primary M7C3 carbide in hypereutectic Fe-Cr-C alloy
The microstructure of the hypereutectic Fe-Cr-C alloy is observed by optical microscopy (OM). The initial growth morphology, the crystallographic structure, the semi-molten morphology and the stacking faults of the primary M7C3 carbide are observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The in-suit growth process of the primary M7C3 carbide was observe...
متن کاملInterdiffusion of Refractory Elements in Fe-Cr-X (X-Mo, W) and Fe-Mo-W Ternary Iron Alloys
Interdiffusion coefficients of the refractory elements in Fe-Cr-X (X 1⁄4 Mo, W) and Fe-Mo-W ternary alloys were measured on the basis of the modified Boltzmann-Matano method for ternary systems. The cross interdiffusion coefficient, ~ D CrW was positive in Fe-Cr-W ternary alloy, indicating that W accelerates interdiffusion between Fe and Cr atoms. On the other hand, the cross interdiffusion coe...
متن کاملCORROSION RESISTANCE OF Co-Cr-Mo ALLOY USED IN DENTISTRY ODPORNOŚĆ KOROZYJNA STOPU Co-Cr-Mo WYKORZYSTYWANEGO W STOMATOLOGII
The presented paper studies the effect of the casting technology on the corrosion resistance of Co-Cr-Mo alloy. The investigations were conducted on a commercial alloy with the brand name ARGELOY N.P SPECIAL (Co-Cr-Mo) produced by Argen as well as the same alloy melted and cast by the lost wax casting method performed by a dental technician. The corrosion behavior of the dental alloys in an art...
