Esilämpökarkaisupäästökäsittely
Esilämpökarkaisupäästökäsittely is a heat treatment process used in metallurgy. It combines two distinct stages: preheating and quenching, followed by tempering. The purpose of this treatment is to achieve a specific combination of hardness and toughness in steel components.
The initial step involves preheating the steel to a predetermined temperature, typically above its critical transformation
The high hardness achieved through quenching, however, comes at the cost of reduced toughness, making the material
