Top-down approach has been viewed as an efficient and straightforward method to prepare nanosized zeolites. Yet, the mechanical breaking of zeolite causes amorphization, which usually requires a post-milling recrystallization to obtain fully crystalline nanoparticles. Herein we present a facile methodology to prepare zeolite nanocrystals, where milling and recrystallization can be performed in ...

A partially recrystallized sample of the Ni-based superalloy AD730 was taken from an intermediate stage ingot to billet conversion process and isothermally forged in a single stroke compression test at sub-solvus temperature (1080 °C). The as-received material had heterogeneous microstructure, containing mixture coarse much finer grains as well unrecrystallized ones, also γ′ precipitation. recr...

During continuous heating of a cold rolled low carbon (LC) steel a dilatometric anomaly has been detected previous to the well known ferrite-to-austenite transformation. This anomaly is due to the texture change and/or the dislocation annihilation that accompany the recrystallization process.
