CHE SIGNIFICA POLYCRYSTAL IN INGLESE
Polycrystal
I materiali policristallini sono solidi composti da molti cristalliti di diversa dimensione e orientamento. La variazione della direzione può essere casuale o diretta, probabilmente a causa delle condizioni di crescita e di elaborazione. La texture della fibra è un esempio di quest'ultima. Quasi tutti i metalli comuni e molte ceramiche sono policristalline. Alcuni elementi come lo zolfo, mentre di solito si verificano in forma policristallina, possono anche verificarsi come singoli cristalli. I cristalliti sono spesso definiti come granuli, tuttavia i grani di polvere sono un contesto diverso. I grani di polvere possono essere costituiti da piccoli grani policristallini. La policristallina è la struttura di un materiale solido che, quando raffreddato, forma granuli cristalliti in punti diversi all'interno di esso. Le zone in cui si incontrano questi grani cristalliti sono conosciuti come confini di grano.
definizione di polycrystal nel dizionario inglese
La definizione di policristallo nel dizionario è un oggetto composto da cristalli orientati casualmente, formati da rapida solidificazione.
