Observations et caractérisations des dislocations dans les monocristaux de titane obtenus par recristallisationThe method of growing nearly perfect titanium single crystals that we elaborated earlier allows us to do an X-ray topography study of dislocations inside this type of crystal. We have ...
Large secondary single crystals of aluminium (30 × 15 × 0.8 mm3) with a small density of dislocations (102 cm/cm3) were grown.doi:10.1016/0022-0248(73)90151-6J. GastaldiP. MarzoC. JourdanElsevier B.V.Journal of Crystal Growth
Etude calorimetrique et cinetique de la recristallisation du cuivre par analyse calorimetrique differentielle (DSC)Pure copper (99.999 %) with various grain sizes was deformed by cold rolling (reduction in thickness 30–90%). DSC curves of energy evolution during recrystallization show that the...
Croissance, par recristallisation secondaire, de gros cristaux exempts de macles dans le cuivre purifié par fusion de zoneOnly zone refined copper, rolled 91%, at 196 掳C, and annealed at 1050 掳C under high vaccum (10 7Corr) yields large twin-free crystals by secondary recrystallization...
Dislocations of aluminium crystals grown under high vacuum (P ⩽ 10-8 torr) by secondary recrystallization at the expense of primary recrystallization cubic texture grains were investigated by X-ray Lang topography. We could see that quasi-linear dislocations, with Burgers vectors making an angle ...
Under certain conditions of temperature and temperature gradient, columnar grains are formed; their diameter is of the same order as that deduced from models based on evaporation-condensation mechanisms.doi:10.1016/0022-3115(70)90079-6Gerard KurkaElsevier B.V.Journal of Nuclear Materials...
