Carbide Dispersion Carburizing (CDC) of Fe-Mo-V Based High-speed Steels

Carbide Structure and Fracture Toughness of High Speed Tool Steels

In the present study, M2 high speed steels were fabricated by using electro-slag rapid remelting process. Carbide structure was analysed and the fracture toughness and hardness were also measured after austenitization treatment at 1190 and 1210C followed by tempering treatment at 535C for billets with various diameters from 16 to 60 mm. Electro-slag rapid remelting (ESRR) process is an advanced...

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...

Effect 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 ...
