Computer Simulation of Recrystallization in Non-uniformly Deformed Metals
The classical Johnson-Mehl-Avrami-Kolmogorov (JMAK) equation [F = 1 exp( kt)“] for nucleation and growth transformations works very well for most solid state transformations but fails regularly when applied to recrystallization of plastically deformed metals. Under conditions of near constant growth rate, a high exponent (n 2 3) is predicted but low exponents (n < 2) are typically measured. Ano...
متن کاملCreep and fracture of metals : mechanisms and mechanics
Modern methodologies that aim to reduce conservatism in the design of components operating at high temperatures rely on accurate predictions of materials’ behaviour in conditions relevant to those experienced in service. This requirement has focussed the attention of materials engineers on developing a quantitative understanding of damage-accumulation in engineering alloys. The microstructure o...
متن کاملDisclination mediated dynamic recrystallization in metals at low temperature
Recrystallization is one of the most important physical phenomena in condensed matter that has been utilized for materials processing for thousands of years in human history. It is generally believed that recrystallization is thermally activated and a minimum temperature must be achieved for the necessary atomic mechanisms to occur. Here, using atomistic simulations, we report a new mechanism o...
متن کاملComment on the papers ‘Creep and recrystallization of large polycrystalline masses’ by Faria and co-authors
In a series of three papers, Faria and co-authors have presented the application of the theory of mixture with continuous diversity to the creep and recrystallization processes of large polycrystallinemasses. In this approach, amaterial point of the continuum is composed of a huge number of grains defined by their crystallographic orientation. The polycrystal is then seen as a continuousmixture...
