“…These types of voids are, however, not seen in the cross-sectional specimen (sample CS). Similar inter-track pores have also been reported previously [37] on cladded-fabricated material that used feedstock powder in the range of 40-140 µm. These types of pores are usually formed if the laser energy input is insufficient to melt all the powdered material introduced in the melt pools.…”

“…In contrast, Smugeresky et al 13 concluded that using smaller 316L steel powder gives a higher hardness, and that surface finish is also a function of particle size. According to Sun et al, 14 the tendency for inter-track porosity formation is higher in laser cladding with finer powder due to its smaller total area. All these studies were conducted with powder of \150 mm.…”

This article investigates the role that particle size and morphology have in determining the final characteristics of a part produced by direct laser deposition. 316L stainless steel in the form of traditional gas-atomised powder and metal shavings in two size ranges were deposited into multiple-layer thin-walled parts at different process parameters. The walls were characterised, considering properties such as geometry, microstructure, composition, physical and corrosive properties and results matched to the type of build material. Results showed that using particles of .150 mm, equivalent spherical diameter offered few functional advantages, leading to a process with lower deposition efficiency and part with lower mechanical properties. Using machined shavings increases deposition efficiency and can reduce gas porosity compared with powder in the same size range, but also results in higher surface oxidation, thought to be due to higher oxidation on the original shavings. This is a barrier for some applications, but the deposition of machined shavings offers significant economic advantages.

“…Stainless steels are widely used in industry since application of such materials leads to increase in service life and reduction of energy consumption [1]. In this regard, precipitation hardened stainless steels with good corrosion resistance, high strength, low distortion, excellent weldability and high hardness (up to 49 HRC), are of considerable interest.…”
