TL;DR: In this paper, experiments were carried out on equilibrium between calcium ferrite slag and metallic copper under a controlled partial pressure of oxygen by using a mixture of CO2 and CO. Lime, magnesia or iron crucibles were used in the temperature range from 1423 to 1623K.
Abstract: Experiments were carried out on equilibrium between calcium ferrite slag and metallic copper under a controlled partial pressure of oxygen by using a mixture of CO2 and CO. Lime, magnesia or iron crucibles were used in the temperature range from 1423 to 1623K. The results were summarized as follows: (1) The solubility of copper in the stags is affected by the oxygen potential and temperature, and the solubility amounts to 70% of that in the case of iron silicate slags. (2) The value of (Fe+++/Fe++) in slags fits the equation previously obtained in the plain FeO-FeO1.5-CaO ternary system, and this ratio in the basic calcium ferrite slags is ten times as large as that in acidic iron silicate slags. (3) The iron contents in metallic copper are related to the oxygen potential, temperature and iron content in the slag. (Received February 19, 1982)

TL;DR: In this article, les textures se forment dans le fer pur polycristallin, on part de differentes dimensions de grains initiales, and le laminage a froid le voisinage des joints de grain de depart dans Fe pur tend a devenir des regions {111} avec une densite elevee de dislocations.
Abstract: Pour mieux comprendre comment les textures se forment dans le fer pur polycristallin, on part de differentes dimensions de grains initiales. Pendant le laminage a froid le voisinage des joints de grain de depart dans Fe pur tend a devenir des regions {111} avec une densite elevee de dislocations. Au cours du recuit qui suit, une germination preferentielle de grains {111} recristallises se produit dans la region du joint de grains initial
