Domain heat treatment
  • termotöötlusprotsess/-operatsioon, mis sisaldab austeniitimist ja järgnevat astekarastamist kiirusega, mis on küllaldane et vältida ferriidi, perliidi või beiniidi teket, kuni temperatuurini pisut üle martensiitmuutuse algtemperatuuri Ms ja seisutamisega, mis on piisav temperatuuri ühtlustamiseks, samas beiniidi teket välides (vt termotöötlus, austeniitimine, astekarastus, ferriit, perliit, beiniit, martensiitmuutuse algtemperatuur)
    Good to know
    • Lõplik jahutamine, mille käigus formeerub martensiit praktiliselt samaaegselt läbi kogu ristlõike, viiakse üldiselt läbi õhus. (vt jahutus, martensiit, martensiitmuutus)
  • heat treatment involving austenitizing followed by step quenching, at a rate fast enough to avoid the formation of ferrite, pearlite or bainite, to a temperature slightly above martensite start temperature Ms, and soaking for a long enough to ensure that the temperature is uniform but short enough to avoid the formation of bainite (see: heat treatment, austenitzing, step quenching, ferrite, pearlite, bainite, martensite start temperature)
    Good to know
    • The final cooling, during which martensite forms practically simultaneously through the cross-section, is generally carried out in air. (see: cooling, martensite, martensitic transformation)
martempering preferred
marquenching
Good to know
  • This variation of the term is usually applied to carburized material.
