High-cycle tensile-tensile fatigue performance of niobium alloy: Conventional vs wire-arc additive manufacturing

Journal of Materials Research and Technology
This study explores the high-cycle fatigue (HCF) behavior of a niobium alloy, NbZr1, fabricated using wire-arc additive manufacturing (WAAM), and compares its fatigue strength to that of its powder metallurgy (PM)-produced counterpart.

Structural integrity of the WAAM-substrate interface

Wire + Arc Additive Manufacturing (WAAM) is a form of directed energy deposition for additive manufacturing of metals. An electric arc is used to melt metal feedstock wire, allowing material deposition in a layer-by-layer fashion. In addition to newly manufacturing workpieces, WAAM could also be applied for the remanufacturing of damaged or worn ...

Infant and Child Mortality in Dublin a Century Ago [PDF]

This paper calculates the concentration index for self-assessed health for a sample of Irish women. It then decomposes the index to investigate the sources of this inequality using both a health production function and reduced form approach.
