“…The major aim of the current work is to extend the method of differential calorimetry to measurements of stored-energy-release spectra in deformed bee metals. In view of the apparent discrepancies and inconsistencies in the past record of storeq-i:mergy measurements, (21,22,23) attention was given during the period of calorimeter development to problems concerning the stored energy of cold work in copper, which has been the most frequently studied metal. The results have provided some resolution, particularly in respect to the effects of grain size, strain, and impurities, and afford useful guidance for the investigations on the bee metals, for which stored-energy-release data are practically nonexistent.…”

In this study, the effects of doping with the surface-active elements Ge, Te, Se, As, Sb and Sn in atomic mass contents of 10 to 200 ppm on the texture and drawability of an IF-steel (FeP06, DIN-EN 10130) and an ELC-steel (FeP05, DIN-EN 10130) were investigated. Twenty-six ingots were produced by melling and doping in a vacuum-induction furnace, followed by forging, hot-rolling and cold-rolling.The cold-rolling reduction was e = 72 %. Recrystallization annealing was performed in~batch-annealing simulation furnace. Subsequently, the orientation distribution function (ODF) and the a, y, n-flbre textures of both the cold-rolled and recrystallized state were measured by means of an X-ray diffraction goniometer and compared with the undoped reference material.The results indicate that the IF-steel specimens doped with 100 ppm Te and Se show a significantly enhanced y-fibre (111}<110>-(111}<112> texture compared to the reference specimen. Also the ELC-steel specimens showed a higher y-fibre by doping with atomic mass contents of 10 to 100 ppm Se and Te. To investigate whether the drawability has been improved, Lankford-value (rmand .M) measurements by means of tensile tests were applied. The compositions with improved y-fibre also showed higher r-values and therefore confirmed the results of the texture measurements. Se doping was found to be especially beneficial in texture and drawability for both investigated materials. The growth of selenides and tellurides at the surface of Ti4C2S2-and Ti2S-precipitates was observed by means of scanning transmission electron microscope Iinescans equipped with field emission gun (STEM·FEG). Doping with Sb and Sn rendered no notable improvement of the materials, and Ge and As proved to affect the mechanical properties unfavourably. Entwicklung neuerTiefziehstahle durch Dotierung mit oberflachenaktiven Elementen. In dieser Arbeit wurde der EinfluB von Dotierungen mit Ge, Te, Se, As, Sb und Sn in atomaren Massenanteilen zwischen 10 und 200 ppm auf die Textur und die Tiefziehfahigkeit eines IF-Stahls (IF18 bzw. FeP06, DIN-EN 10130) und eines ELC-Stahls (St15 bzw. FeP05, DIN-EN 10130) untersuchl. Insgesamt wurden 26 Schmelzen im Vakuuminduktionsofen dotiert und durch Schmieden, Warmwalzen und Kaltwalzen weiterverarbeitel. Der Kaltwalzgrad betrug e = 72 %, um die senkrechte, mittlere Anisotropie fin zu optimieren. Die Proben wurden anschlieBend durch eine Haubensi-mulationsglOhung rekristallisiert. Millels eines Rontgentexturgoniometers wurden je drei Polfiguren gemessen, daraus die Orientierungsverteilungsfunktion (ODF) berechnet, aus dieser die a, y und n-Fasertexturen bestimmt und mit denen des undotierten Ausgangsmaterials verglichen. Als mechanische KenngroBen der Tietzlehtahlqkelt wurden im Zugversuch die Werte der senkrechten und der planaren Anisotropie r m und sr bestimml. Weiterhin wurden an den dotierten Proben Mikrostrukturuntersuchungen millels Feldionenmikroskop mit Atomsonde (AP-FIM) und Rastertransmissionselektronenmikroskop mit Feldemissionskanone (STEM-FEG) durchgefOhr...
