Additive manufacturing (AM) has been intensively studied over this decade due to the increasing demand of functional and precise materials in various industries. AM process leverages on the concept of layer by layer deposition or joining of a material at micro‐ or nano‐scale to produce the final products. As such, AM technology is widely used to manufacture products of complex geometries with high precision in a short time. As the quality and the performance of AM manufactured functional products depend on the quality and the cost of the atomized metal or alloy powder used, the use of powders of high size uniformity, high purity, high sphericity, high flowability, low cost, and no trapped gas bubble porosity is necessary. To this end, various metal production technologies were investigated and one of the popular technologies is atomization. This article reviewed the working principles of the various atomization technologies for the production of fine metal and alloy powders. The key atomization conditions discussed in this article include atomization type, material feed rate and temperature, atomizing fluid flow rate, type and temperature, cooling rate, and atomization pressure. In addition, several outlooks on the prospect and the optimization of atomization technologies were also discussed in this article.

The space debris management and alleviation in the microgravity environment is a dynamic research theme of contemporary interest. Herein, we provide a theoretical proof of the concept of a lucrative energy conversion system that is capable of changing the space debris into useful powders in the International Space Station (ISS) for various bids. A specially designed broom is adapted to collect the space debris of various sizes. An optical sorting method is proposed for the debris segregation in the ISS by creating an artificial gravitational field.It could be done by using the frame-dragging effect or gravitomagnetism. An induction furnace is facilitated for converting the segregated metal-scrap into liquid metal. A fuel-cell aided water atomization method is proposed for transforming the liquid debris into metal powder. The high-energetic metal powders obtained from the space debris could be employed for producing propellants for useful aerospace applications, and the silicon powder obtained could be used for making soil for fostering the pharmaceutical-flora in the space lab in the future aiming for the scarce-drug discoveries for high-endurance health care management. The proposed energy conversion system is a possible alternative for the space debris extenuation and its real applications in orbiting laboratories through the international collaboration for the benefits to humanity.

The AZ91D-SiC composite powder was produced from machining chips using the mechanical milling and alloying processes as an effective recycling method. The mechanical milling and alloying were conducted in a high-energy planetary ball mill. The effects of milling time and ball-to-powder weight ratio (BPR) on the morphology, distribution uniformity, and powder yield were evaluated. In the mechanical milling process, the four stages of chip milling were investigated. The optimum conditions of the milling were equal to milling for 10 h and a BPR of 25:1. The powder yield was at its maximum value and did not change much by changing the milling conditions. In the mechanical alloying, a higher BPR had a more significant effect on the uniform distribution of the particles compared to a higher milling time. The uniformity of the particle distribution is higher for 5 h alloying and a BPR of 20:1. A new peak in the XRD pattern of the composite powder obtained did not appear during the mechanical alloying process. It was observed that the amount of reinforcement phase has little effect on the particle size of the composite powder, while the particle distribution was improved by reducing it up to 40%.
