Superplastic hemispherical Bulge Forming of a Ti-Al-Mn Alloy
Superplastic sheet thermoforming has been identified as a standard processing route for the production of complex shapes, especially in the aerospace industry. Ti-Al-Mn (OT4-1) alloy is currently being used for aero engine components as well as other aerospace applications by forming through a conventional route which is typically cost, labour and equipment intensive. The Ti-Al-Mn alloy (made a...
متن کاملYielding Phenomenon of an Al-3% Li Alloy
where the specimens are recovered but not recrystallized. This second type of yielding is characterized by a sharp yield drop and long yield elongation. A mechanism of the second type of yielding has not been investigated, but it is clear that the yielding phenomenon is not due to a simple effect of strain aging, because the specimens has recovered so that dislocation arrangements should have c...
متن کاملGradient Distribution of Martensite Phase in Melt-Spun Ribbons of a Fe-Ni-Ti-Al Alloy
Metallographic, X-ray diffraction and magnetometric analysis were used to study the regularities of martensitic transformation in melt-spun ribbons of a Fe - 28 wt. % Ni - 2.1 wt. % Ti - 2 wt. % Al - 0.05 wt. % C alloy. The substantial differences in volume fractions of the martensite phase in local regions of thin melt-spun ribbons of the alloy are related to the size effect of the transformat...
متن کاملMicrostructure and Grain Refining Performance of a New Al-Ti-C Master Alloy (RESEARCH NOTE)
Control of microstructure parameters that affecting the Al-Ti-C master alloys grain refining efficiency is leading to improve the aluminum grain refinement. This study was an attempt to produce Al-Ti-C master alloys that provide these controlling factors with relying on the solute effect theory. The produced master alloys were examined by using scanning electron microscopy (SEM), energy-dispers...
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...
