The specific heat capacity is small, and the temperature inside and outside the part is consistent when the structure is changed, so the quenching structure stress is also small. Austempering and staged quenching can only be applied to smaller parts.
Web1 de abr. de 2011 · On the other hand, when the samples are deformed at high temperature (970 °C), the deformation extend of α phase is small and dynamic recrystallization of α phase is restrained but the dynamic coarsening of α p grains is remarkable at high temperature so that the grain size of α p varies little with deformation degree at high …
