Improving the tensile strength of carbon nanotube spun yarns using a modified spinning process [PDF]
, 2009 A modified process for the dry spinning of carbon nanotube (CNT) yarn is reported. The approach gives an improved structure of CNT bundles in the web drawn from the CNT forest and in the yarn produced from the twisted web leading to improved mechanical ...

Tensile properties of carbon nanotube fibres described by the fibrillar crystallite model [PDF]
, 2019 This work presents a model that successfully describes the tensile properties of macroscopic fibres of carbon nanotubes (CNTs). The core idea is to treat such a fibre as a network of CNT bundles, similar to the structure of high-performance polymer fibres, with tensile properties defined by the CNT bundle orientation distribution function (ODF), shear ...

Le Journal de Physique IV, 1997 The experimental method of the testing at a high speed machine with ram speed of l-l0m/s is described. The reproducibility and the effects of the material and the ram speed on the oscillations in measured load have been studied. A software for subtracting the oscillations, which seem to come mainly from the load measurements system, from the recorded ...

Advanced Engineering Materials, EarlyView.Temporal power modulation increases weld depth in high‐power laser beam welding of dissimilar round bars by nearly 20% compared to same average continuously welded welding power. The mechanism of action also applies to sheet welding and depends on the inertia of keyhole depth for the modulated laser beam power.

Advanced Engineering Materials, EarlyView.In this study, how friction‐welding parameters (rotational speed, etc.) affect the morphology, distribution, and local thickness of the intermetallic compound layer (IMC‐layer) in friction‐welded steel‐aluminum hybrid components is investigated. In the results, it is shown that lower speeds (700 rpm) lead to a more uniform, thinner IMC‐layer (<0.5 μm),

Deformation-induced grain growth and twinning in nanocrystalline palladium thin films
Beilstein Journal of Nanotechnology, 2013 The microstructure and mechanical properties of nanocrystalline Pd films prepared by magnetron sputtering have been investigated as a function of strain. The films were deposited onto polyimide substrates and tested in tensile mode.

An Apparatus for Tensile Testing of Engineering Materials [PDF]
Experimental Mechanics, 2018 We develop a novel apparatus and an associated test protocol to measure the tensile response of materials. The apparatus allows testing of ring-shaped specimens, fibre yarns and tapes of arbitrary length; it can be employed to conduct experiments at different strain rates and in different environmental conditions.

Advanced Engineering Materials, EarlyView.This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.
