Reductions of Intergranular Corrosion Resistance and Wear Resistance in a Ni-Cr-Mo-Based Superalloy by Aging-Treatment-Induced Precipitation
نویسندگان
چکیده
Ni-Cr-Mo-based superalloy is widely used as a key component in many critical environments. To ensure that the manufacturing process does not impact long-term service performance of these components, aging precipitation behavior at different temperatures and its effect on intergranular corrosion (IGC) resistance wear C276 were investigated. The equilibrium phase diagram was calculated first using thermodynamic software to confirm potential phases. Carbides M6C found be formed grain boundaries after 800–850 °C for short-term treatment. other two phases (μ P phase) indicated observed samples treatment up 15 h. Furthermore, double loop electrochemical potentiokinetic reactivation (DL-EPR) tests conducted examine IGC resistance. degree sensitization increased with time severe occur boundaries. For time, influence this has been specifically studied. Concerning hot processing superalloy, results indicate importance avoiding high-temperature heat long periods.

CORROSION 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...
متن کاملCreep of Ni-Al and Ni-Cr-Al Superalloy Foams
The steady-state creep rate of Ni-base metallic foams, with superalloy composition (in wt. pct) Ni7.8∼9.1Al (relative density, ρ = 2.5-2.6) and Ni-13.5∼16.6Cr-5.1∼8.9Al (ρ = 2.8∼3.0), was measured under a range of temperatures (680∼825°C) and applied stresses (0.1∼0.3 MPa), and compared with that of NiAl intermetallic foams (ρ = 5.3). The stress exponent and activation energy are within the exp...
متن کاملThe Role of Alloying Elements on the Crevice Corrosion Behavior of Ni-Cr-Mo Alloys
The roles of the alloying elements Mo, Cr, and W in resisting crevice corrosion of UNS N06022, UNS N06625, and UNS N10362 have been studied under galvanostatic conditions in 5 mol/L NaCl at 150°C. Corrosion damage patterns were investigated using surface analytical techniques such as scanning electron microscopy and optical imaging, and the corrosion products characterized by energy dispersive ...
متن کاملPrecipitation in a Ni - Al - Mo Directionally Solidified Eutectic Composite
The most recently developed high temperature materials are known as in-situ composites or directionally solidified eutectics. Since the composites are formed during solidification, they have excellent morphological stabilities up to near their melting temperatures. The Ni-Al-Mo system has received the greatest attention for recent several years(1)~(3) since the alloy is expected to form a struc...
