Anomalous yielding in the complex metallic alloy Al13Co4
The single crystal deformation behaviour of orthorhombic Al13Co4 has been studied below the brittle-ductile transition temperature observed in bulk material from room temperature to 600 C, using indentation, microcompression and transmission electron microscopy. At room temperature, slip occurred most easily by dislocation motion on the (001)[010] slip system, as observed in the ductile regime ...
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...
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 کاملStrain glass transition in a multifunctional β-type Ti alloy
Recently, a class of multifunctional Ti alloys called GUM metals attracts tremendous attentions for their superior mechanical behaviors (high strength, high ductility and superelasticity) and novel physical properties (Invar effect, Elinvar effect and low modulus). The Invar and Elinvar effects are known to originate from structural or magnetic transitions, but none of these transitions were fo...
متن کاملPseudo-elastic deformation behavior in a Ti/Mo-based alloy
It is shown that the pseudo-elastic response in a series of Ti–Mo–V–Nb–Al alloys with 8–11 wt.% Mo is highly sensitive to both composition and heat treatment. Recovery of up to 3.0% strain has been observed but it appears that this may not be due to reversible formation of a00 martensite. 2003 Acta Materialia Inc. Published by Elsevier Ltd.
