Study of the Kinetics of Static Recrystallization Using Avrami Equation and Stress Relaxation Method

Popis výsledku v původním jazyce

In order to design and use forming processes, one has to cover a body of knowledge including the recovery phenomena. Recovery can be described using the Avrami equation, which yields the proportion of recrystallized structure as a function of various deformation-related variables. However, some constants and exponents of the equation must be known. Their values can be obtained by measuring ? either by metallographic or mechanical methods ? the fraction of recrystallized structure in specimens deformed under prescribed conditions. A metallographic technique consists in quenching the material and mapping the locations of grains, their sizes and shapes in an optical microscope to find the ratio of recrystallized grains. It is possible to use a more up-to-date technique: electron microscopy combined with electron backscattered diffraction. However, these methods are in fact very complicated and often infeasible. Mechanical methods include intermittent tests in compression or torsion plasto
