Novel Application Research on Critical High-Temperature Deformation of Low-Lead Brass Alloy

Metals, 2020
This study investigated the critical high-temperature deformation of the low-lead (Pb) Cu38Zn3Pb alloy. Moreover, the dezincification mechanism of this alloy for high-temperature applications was evaluated.

Experimental study on dynamic mechanical behavior of frozen sandstone with different saturations

Meitan kexue jishu, 2023
Water content is one of the critical factors affecting frost damage to rock masses in alpine regions. A dynamic disturbance load further complicates the issue.

Nature of the Brittleness of Metals

Успехи физики металлов, 2022
The brittleness of material is considered as a specific manifestation of mechanical behaviour under load, which appears in the instability of the strength characteristic value under conditions of non-uniformity of the stress–strain state (SSS).

Sn-3.0Ag-0.5Cu/Sn-58Bi composite solder joint assembled using a low-temperature reflow process for PoP technology

Materials & Design, 2019
Package-on-Package (PoP) is a popular technology for fabricating chipsets of accelerated processing units. However, the coefficient of thermal expansion mismatch between Si chips and polymer substrates induces thermal warpage during the reflow process ...

Assessment of the Hot-Cracking Susceptibility of Welded Joints of the 7CrMoVTiB10-10 Bainitic Steel Used in Heat Exchangers

Energies, 2022
Bainitic steel containing approx. 2.25% Cr and 0.6 Mo with micro-additions of V, Ti, and B, designated as 7CrMoVTiB10-10 (T/P24), is one of the new construction materials used in new supercritical power units. The weldability of 7CrMoVTiB10-10 is defined

On the Critical Temperature for Propagation of Brittle Crack in Steel Plate

Journal of Zosen Kiokai, 1960
Adopting the idea of double tension test developed at University of Tokyo, the author investigated the behaviours of steel plates to propagation of brittle crack under the similar condition to the service. Critical temperatures for crack propagation defined on the double tension transition curves by the same stress level as the design stress were found

Dynamic Mechanical Behavior of the Frozen Red Sandstone under Coupling of Saturation and Impact Loading

Applied Sciences, 2022
Saturation is one of the critical factors causing frost damage to rock masses in alpine regions, and dynamic stress perturbations further complicate the damage process.

Effect of temperature on the mechanical performance of plywood used in membrane-type LNG carrier insulation systems

Journal of Wood Science, 2020
In this study, the mechanical performance of melamine–urea–formaldehyde (MUF) resin plywood composed of an orthotropic material, which is used as a structural material in liquefied natural gas (LNG) cargo containment systems (CCSs), is evaluated.
