Dynamic Recrystallization in Titanium Alloys
Key Engineering Materials, 2016The results of the investigations on five different titanium alloys were presented in this paper. Two two-phase α+β alloys (Ti-6Al-4V and Ti-6Al-2Sn-4Zr-6Mo) as well as two β alloys (Ti-10V-2Fe-3Al and Ti-3Al-8V-6Cr-4Mo-4Zr) were studied. Moreover, Ti-48Al-2Cr-2Nb intermetallic alloy (γ alloy) was also investigated.

Dynamic Recrystallization in Tial Alloys
MRS Proceedings, 1992TiAl alloys with Cr, V, and Nb additions show promise as high temperature materials due to their high temperature strength and modulus. Dynamic recrystallization has been shown to be important for the processing and superplastic forming of these materials.

Dynamic recrystallization of zirconium carbide
Scripta Metallurgica, 1976Results of compression testing of ZrC are presented which show that in the range 1200 to 1800$sup 0$C these materials may undergo dynamic recrystallization. The predominant deformation mechanism near the yield stress is carbon diffusion-assisted motion of dislocations.

A model of continuous dynamic recrystallization
Acta Materialia, 2003During continuous dynamic recrystallization (CDRX), which occurs in high stacking fault energy metals, new grains are formed by the progressive increase of low-angle boundary misorientations. A simple CDRX model is proposed, that deals with a set of “crystallites” delimited partly by low-angle (LABs) and partly by high-angle (HABs) boundaries.

Modelling of Dynamic Recrystallization in Hot Working
Key Engineering Materials, 2007Dynamic recrystallization, on which grain size of the final forging depends mainly, is one of the most important microstructure evolution processes in moderate-to-low stacking fault energy metals. In this paper, the process of dynamic recrystallization is simulated by numerical method.

It is well-known that strain-induced grain growth is a characteristic feature of superplastic deformation (SPD) of various materials. Such grain growth has been observed over the whole investigated interval of strains in quasi-single phase superplastic aluminum alloys 7475, Neopral and 5083.

The hot deformation characteristics of a novel nickel‐based superalloy is investigated via the isothermal compression test in temperature range of 1000–1150 °C and strain rate of 0.001–10 s−1 under the true strain of 0.8.

A Different View on Dynamic Recrystallization
Materials Science Forum, 2012A new approach to dynamic recrystallization (DRX) is introduced. It is based on the assumption that the critical conditions for DRX and the arrest of DRX grain boundaries are related to the development of mobile subboundaries. The theoretical predictions are compared to experimental results during incipient and steady-state DRX.

Phase-Field Modeling for Dynamic Recrystallization [PDF]
, 2015 Hot working is a process in which metallic materials are worked at the elevated temperatures above the recrystallization temperature. During the hot working of the low-to-medium stacking fault energy metals, the dynamic recrystallization (DRX) occurs.
