CHEMICAL COMPOSITIONS OF ULTRAFINE LAMELLAE IN THE WATER-QUENCHED Ti-48Al ALLOY
As Ti rich Ti-Al alloy shows ductile nature with the α2 + γ lamellar structure [1], the mechanism of microstructural evolution in Ti-Al alloys has attracted much interest. Since the lamellar structure is formed by the continuous cooling in industrial processes, cooling rate dependence of α → γ and α → α2 + γ transformations has been extensively studied by many researchers [2-5]. Wang et al. [2,...
متن کاملLow Temperature Phase Transformations in Copper-Quenched Ti-44.5Al-8Nb-2.5V Alloy
In this study, an easily controlled transformation similar to the β + α → β + α + γ and the analysis of metastable phases in a β solidifying Ti-44.5Al-8Nb-2.5V alloy were investigated. Therefore, a liquid alloy copper-quenching followed by annealing at an application temperature (850 °C) has been carried out. Following quenching, a microstructure composed of several supersaturated phases-the ba...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولEffects of partial crystallinity and quenched-in defects on corrosion of a rapidly solidified Ti–Cu alloy
Rapid solidification by planar flow casting has been found to have introduced deficiencies, viz. partial crystallinity, air pockets and compositional difference in the ribbons of rapidly solidified Ti42⋅9Cu57⋅1 alloy. In order to investigate the effects of these deficiencies on the corrosion of rapidly solidified Ti42⋅9Cu57⋅1 alloy ribbons, electrochemical behaviour of alloy ribbons has been in...
متن کاملDental casting of superelastic Ni-Ti alloy.
Rods of Ni-43.5wt% Ti alloy were prepared under various casting conditions. Specimens which were melted in a cordierite crucible and cast in a phosphate-bonded investment mold had less strength and elongation than those melted in a copper crucible and cast in a phosphate-bonded investment mold. All castings exhibited superelasticity at room temperature. The upper limit of recoverable strain was...
