Additive manufacturing offers a significant potential for producing metallic parts with distinctly localised microstructures and mechanical properties, commonly known as functional grading. While functional grading is generally accomplished through c

The absorptivity of a material is a major uncertainty in numerical simulations of laser welding and additive manufacturing, and its value is often calibrated through trial-and-error exercises. This adversely affects the capability of numerical simula

Understanding what happens to the liquid in melt pools during welding and metal-based additive manufacturing remains a challenge. Here, the authors directly image internal melt pool dynamics using synchrotron radiation to show surface tension affects

One of the challenges for development, qualification and optimisation of arc welding processes lies in characterising the complex melt-pool behaviour which exhibits highly non-linear responses to variations of process parameters. The present work pre

The high degree of uncertainty and conflicting literature data on the value of the permeability coefficient (also known as the mushy zone constant), which aims to dampen fluid velocities in the mushy zone and suppress them in solid regions, is a crit

Background Patient memory for psychological treatment contents is a promising transdiagnostic mechanism of change, but there is little consensus concerning its measurement. We conducted a pilot psychometric investigation of the Conceptualization Task

Numerous American and European studies have shown that ill health is a common cause of difficulty in work, retirement, and restricted participation in social activities. The specific disabilities which commonly lead to retirement are fairly well-defi
