jäähtymisprofiilia
Jäähtymisprofiili, or cooling profile, is the record of temperature change over time during the cooling of a material from an elevated state to a lower temperature. It is used primarily in metallurgy and heat‑treatment processes to characterize how quickly or slowly an alloy loses heat, which in turn influences its microstructure, mechanical properties, and residual stresses. The profile is obtained by embedding a thermocouple or other temperature sensor in the material or placing it in close proximity, then recording the temperature as the material is cooled, either naturally in ambient air, in a controlled furnace, or with forced convection or quenching media.
The shape of a cooling profile is described by key parameters such as the cooling rate, which
Modern laboratories use computerized data acquisition systems to generate cooling profiles with high temporal resolution. By
