The Cracking Mechanism of Ferritic-Austenitic Cast Steel

Archives of Foundry Engineering, 2016
In the high-alloy, ferritic - austenitic (duplex) stainless steels high tendency to cracking, mainly hot-is induced by micro segregation processes and change of crystallization mechanism in its final stage.

Quantification of large and localized deformation in granular materials [PDF]

, 2011
Quantifying large deformation in granular assemblies using concepts originating from continuum mechanics is a challenging task because of (1) the discontinuous nature of granular displacement, which does not allow the definition of a continuum measure of

The effect of thermomechanical processing on the piezoelectric and electrical conductivity of PLA/2.5%MWCNT composite

Journal of Materials Research and Technology, 2023
The electrical properties of polymer materials, such as electrical conductivity and piezoelectricity, are significantly influenced by the ratio of amorphous to crystalline regions. Additionally, the alignment of added particles and formed crystallites is

Flow Behavior and Mechanical Properties of Multi-Pass Thermomechanically Processed 7075 Al-Alloy

Metals, 2023
Research on multi-pass hot processing of 7075 Al-alloy was rarely discussed. This study aims to design and evaluate different thermomechanical processing strategies (TMPS) to produce 3 mm-thick sheets of 7075 Al-alloy. A physical simulation was performed

Dynamic strain aging and twin formation during warm deformation of a novel medium-entropy lightweight steel

Journal of Materials Research and Technology, 2022
The present study deals with the extraordinary twin formation during compressive deformation of a Fe-37.55Mn-8.5Al-0.6C (wt.%) low-density steel at warm temperature regime (200–600 °C). Despite the conventional opinion regarding the restrictive effect of

p-deformation

Differential Equations & Applications, 2022
Summary: In this article we introduce the so called \(p\)-deformed algebra \(\mathcal{V}\). The notion of \(p\)-deformation is connected to the well-known \(q\)-deformation by the simple relation \(p = \frac{q^2+q^{-2}}{2}\). Thus the \(p\)-deformed algebra \(\mathcal{V}\) will have representations in terms of \(q\)-difference operators.

Optimizing weathering steel tie rod production for sustainable greenhouse structures

Scientific Reports
The current paper is based on a case study conducted at an industrial facility in Egypt, which is responsible for processing greenhouse structures. Steel tie rods play a vital role, as they prevent the truss frames from spreading outwards. Irrigation and

Integrating the Finite Element Method with Python Scripting to Assess Mining Impacts on Surface Deformations

Applied Sciences
Mining operations disrupt the structure of rock layers, leading to surface deformations and potential mining damage. This issue has been extensively studied since the 19th century using various analytical, geometric-integral, and stochastic methods ...
