English term or phrase: martempering
Definition from Engineering Dictionary:
Quenching an austenitized ferrous alloy in a medium at a temperature in the upper part of the martensite range, or slightly above that range, and holding it in the medium until the temperature throughout the alloy is substantially uniform. The alloy is then allowed to cool in air through the martensite range.

Example sentence(s):
  • The primary advantage of martempering is that parts will have lower distortion and reduced residual stress. GEARSolutions
  • The present study shows the results in terms of mechanical properties, impact resistance in special of a cold work tool steel class, after being heat treated by the isothermal modified martempering process, as well as a comparison with the conventional quenching and tempering process and the austempering as well. Research Gate
  • Annealed samples have less carbide in micro structure and are least hard, whereas martempered samples have dense carbide indicating highest hardness. Hardness increased three times with martempering process Hindawi

Definition from https://ro.qaz.wiki/wiki/Martempering:
Martempering este, de asemenea, cunoscut sub numele de stingere (călire) în trepte sau stingere (călire) întreruptă . În acest proces, oțelul este încălzit deasupra punctului critic superior (peste intervalul de transformare ) și apoi stins într-o baie de sare , ulei sau plumb menținută la o temperatură de 150-300 ° C.

Example sentence(s):
Explanation:
calirea in trepte sau izoterma – piesa se raceste la inceput intr-un mediu capabil sa asigure o viteza de racire suficient de mare pana la o temperatura usor superioara punctului Ms, dupa care urmeaza o mentinere izoterma pentru o anumita durata (minute), pentru ca temperatura sa devina uniforma in toata masa piesei.
