From: Double twist torsion testing to determine the non recrystallization temperature
Microstructures generated using double-hit compression with the compression axis horizontal to the page (a) above Tnr at 1150 °C, (b) near Tnr at 1100 °C, and (c) below Tnr at 1050 °C. Specimens were electrochemically etched in a 60 pct nitric acid and 40 pct water solution.
