Mechanical properties of steel no. 45 after rapid heat treatment

Technology of Heat Treatment


  1. 1.

    Rapid heat treatment at the same quenching and tempering temperatures strengthens steel more than ordinary heat treatment (in which the samples are kept at the tempering temperature for a certain time). The quality coefficients are about the same after the two types of heat treatment.

  2. 2.

    We determined the relationship between the heating rate and the quenching and tempering temperatures.

  3. 3.

    We determined the variation of the mechanical properties as a function of the conditions of rapid heat treatment. These data make it possible to define the optimal conditions to obtain the desired properties at different heating rates.

  4. 4.

    It was found that for thin walled objects one can successfully replace ordinary heat treatment (requiring the object to be kept at high temperatures for a certain time) with rapid heat treatment, thus increasing production efficiency.
