Reversible Temper Brittleness

Low-temperature nitriding of steels is usually carried out in the temperature range of development of reversible temper brittleness. The holding time at these temperatures significantly exceeds the holding time during normal tempering, which can negatively affect the properties of steel. The article considers theories that explain the processes occurring in steels in the temper brittleness temperature range. It may be concluded that views linking the embrittlement of steel with alloying elements such as nickel in its content are not confirmed by the experiments; at the same time ideas based on classical views about the diffusion of chemical elements explain the processes in steel better.

The modification of mechanical properties (maximum bending strength and deflection, hardness and impact strength) of tool steels whose primary alloying elements are either chromium, tungsten, tungsten and molybdenum, or chromium and molybdenum by low temperature thermomechanical treatment (LTTMT) by rolling with deformations up to 20 percent and extrusion with 60 percent deformation has been investigated. The high chromium tool demonstrated the greatest consistent improvements in strength (40 percent) and deflection (55 percent) for LTTMT over conventional heat treatment. The influence of the LTTMT process on the microstructure of the chromium and tungsten steels is investigated by fractography using a scanning electron microscope. The tungsten steel and the extrusion process yielded a finer distribution of hard particles in the ductile matrix than did the chromium steel and rolling.
