Room Temperature Tensile Test of Cu/Nb-Ti Composite Superconductors.

Tensile deformation mechanisms of an in-situ Ti-based metallic glass matrix composite at cryogenic temperature

Remarkable tensile ductility was first obtained in an in-situ Ti-based bulk metallic glass (BMG) composite at cryogenic temperature (77 K). The novel cryogenic tensile plasticity is related to the effective accommodation of ductile body-centered cubic dendrites at 77 K, characteristic of the prevailing slip bands and dislocations, as well as lattice disorder, which can effectively hinder the pr...

Revealing extraordinary tensile plasticity in layered Ti-Al metal composite

Layered Ti-Al metal composite (LMC) fabricated by hot-pressing and hot-rolling process displays higher ductility than that of both components. In this paper, a combination of digital image correlation (DIC) and X-ray tomography revealed that strain delocalization and constrained crack distribution are the origin of extraordinary tensile ductility. Strain delocalization was derived from the tran...

Abnormal Plastic Behavior of Fine Grain Mp35n Alloy During Room Temperature Tensile Testing

In this paper, results of an investigation on the strain hardening responses of superalloy MP35N with two average grain sizes of 38 and 1 μm, during room temperature tensile testing are reported. The microstructural evolution of the deformed samples was studied using optical and transmission electron microscopy (TEM) techniques. The strain hardening behavior of the 38 μm material was rather sim...

Room and high temperature tensile behaviour of a P / M 2124 / MoSi 2 composite at different heat treatment conditions

Quench energies of composite superconductors

The minimum energy of a local heat pulse Qo, initiating normal zone propagation is an important characteristic of the stability of a superconducting composite. There are many papers concerning, both experimentally and theoretically (usually numerically), the value of Qc for composite superconductors (see, e.g., References 1-3 and references therein). In particular, simple analytical formulae fo...
