Thermodynamic Simulation of Gas Carburizing of Steels
Simulation of metallurgical processes has been the subject of intense research due to the reduced number of experiments required for controlling the process as well as time and energy savings it allows. In gas carburizing of steel parts, the amount of carbon at the surface of carburized parts is the most important specification of the process in terms of achieving the desired metallurgica...
متن کاملTHE OXIDATION RESISTANCE OF HIGH ALUMINUM HEAT RESISTANT STEELS
Abstract: In this research, the oxidation behaviour of high Aluminum heat resistant steel (%25Cr,%20Ni,%8Al) hasbeen evaluated at the temperature range of (1000-1300ºC).The results showed that there was no countinous healinglayer on the surface of the alloy when Al increased up to %5.5 and the oxidation resistance of steel decreased due toformation of spinel oxides on the surface.By increasing ...
متن کاملEffect of Heat Treatment and Case Carburizing High-Density P/M Steels
Recent advancements in high-density lubricants enable P/M steels to be processed to densities approaching 7.40 g/cm in a single compaction step using heated compaction tools via the AncorMax D process. This broadens the number of suitable applications for P/M steels, including high performance gears. However, in addition to high-density, the microstructural and mechanical property requirements ...
متن کاملInfluence of silicon on cementite precipitation in steels
The mechanism by which relatively small concentrations of silicon influence the precipitation of cementite from carbon supersaturated austenite and ferrite are investigated. It is found that one condition for the retardation of cementite is that the latter must grow under para-equilibrium conditions, i.e. the silicon must be trapped in the cementite. However, this is not a sufficient condition ...
متن کاملDilatometric analysis of cementite dissolution in hypereutectoid steels containing Cr
Cementite dissolution in hypereutectoid steels containing Cr is analyzed using dilatometry combined with the consideration of the carbon content in the austenite. The results suggest that the austenite transformed from the mixture of ferrite and cementite can be approximated to have a carbon content corresponding to equilibrium with ferrite. The overall dissolution behavior of cementite is desc...
