In the current investigation, a comparison between two type 4130 low-alloy steel powders
produced by both gas and water atomization, and later processed by Laser-powder bed …

A water atomized 4130 steel powder was processed by Laser powder bed fusion and
investigated both in as-built condition and after quench and tempering thermal treatment …

We develop a pre-alloyed water-atomized (WA) iron powder for laser powder bed fusion
(LPBF)-based 3D printers; such a powder has never been used for 3D printing. The powder …

The microstructure and mechanical properties of a 4130-grade steel processed by L-PBF
using a feedstock of low-cost water atomized powder have been investigated considering …

As additive manufacturing (AM) shows great promise in generating functional parts, the list
of printable ferrous alloys is growing steadily. Low‐alloy steels are such alloys that hold the …
