Tensile Testing with Cyclic Strain Holding to Analyze Dynamic Recrystallization of Pure Lead

Advances in Materials Science and Engineering, 2014
We analyzed the dynamic recrystallization of pure lead by tensile testing with cyclic strain holding at room temperature. The specimens were held at an identical strain and subsequently reloaded, providing the strength before and after the strain holding

Inferring dynamic recrystallization in ferrite using the kinetics of static recrystallization [PDF]

Metallurgical and Materials Transactions A, 2002
A general relationship between the kinetics of dynamic and static recrystallization is developed. It is predicted that conventional dynamic recrystallization will occur whenever the deformation time exceeds the adjusted start time for static recrystallization. This approach is verified using data for austenite and lead.

Evaluation and Training of Dynamic Recrystallization phenomenon in an Al-Li-Cu-Zr(-Mg) Alloy [PDF]

Fanāvarī-i āmūzish, 2008
In this research, dynamic recrystallization of an Al-Li alloy was investigated in two temperatures, i.e. 350°C and 400°C. Wedge samples were subjected to hot rolling deformation in high temperature and one passes. For wedge specimens, reduction up to 70%
