On recrystallization of Al-Ag and Al-Cu alloys

Abstract

The recrystallization temperatures of solution treated and normalised alloys were determined by X-ray method. In the case of Al-Ag, solution treated alloy did not recrystallize up to the temperature of the solubility limit, but that of normalised alloy is not so high. In the case of Al-Cu, the effects of solution treatment on the recrystallization temperature are not so marked. The relation between the plane of precipitation of the precipitant and the slip plane is different from each other of the two alloy systems; the resistance being about the same as that due to the resistance of the precipitant to the recrystallization (Received July 28, 1958) Table 1 Chemical composition of specimens.

“…To estimate the switcbg behavior we developed a time-inkgation of the external field, Wt), over the switching field, K,, as j(H(t)-HcmW [4,5]. Recently we suggested that a medium wiih high anhmpy field, 4, would switch faster [5].…”

Recently we suggested that a medium wiih high anhmpy field, 4, would switch faster [5]. The writing process of square-wave recording were well investigated by numerical calculation [3,4,6,7], but the relation between the recording limit at high cbta-hansfer rafe and & of the media is not clear.…”
