“…In the two similar works by Zhao et al and Li et al, the effect of MAF and heat treatment conditions on the microstructure of additively manufactured Inconel 718 super-alloys was studied [ 87 , 88 ]. The combination of the two treatments provided a reduction in surface roughness, refinement in grain size, and improvement in alloy elongation.…”

Fast progress in near-net-shape production of parts has attracted vast interest in internal surface finishing. Interest in designing a modern finishing machine to cover the different shapes of workpieces with different materials has risen recently, and the current state of technology cannot satisfy the high requirements for finishing internal channels in metal-additive-manufactured parts. Therefore, in this work, an effort has been made to close the current gaps. This literature review aims to trace the development of different non-traditional internal surface finishing methods. For this reason, attention is focused on the working principles, capabilities, and limitations of the most applicable processes, such as internal magnetic abrasive finishing, abrasive flow machining, fluidized bed machining, cavitation abrasive finishing, and electrochemical machining. Thereafter, a comparison is presented based on which models were surveyed in detail, with particular attention to their specifications and methods. The assessment is measured by seven key features, with two selected methods deciding their value for a proper hybrid machine.

Many engineering applications require components with a good surface finish. It is difficult to get the surface finish in the micro/nano level range with conventional finishing processes for materials such as super alloys, composites, and ceramics. Magnetic abrasive finishing (MAF) is one of the processes for achieving superior surface finish. However, the processes efficiency is affected by its operational variables. Even a slight change in a processing parameter may lead to dimensional inaccuracies and poor surface quality of the workpiece. In this paper, recent trends in the magnetic abrasive finishing process are presented along with a critical review. The review includes MAF principles, tools, hybridization, modeling, and simulation of the process. Apart from plane MAF, the principle of MAF for cylindrical workpieces, the mechanism of material removal and the effect of different types of abrasives are also discussed. Various machine tools used for MAF of plane and cylindrical workpieces for external and internal surfaces are also discussed. In hybridization, different processes combined with MAF, like ultrasonic-assisted MAF, chemo-assisted MAF, and electrochemical-assisted MAF, etc., are discussed to increase material removal rate and obtain surface finish at the micro/nano level. The paper also covers mathematical and statistical modeling, simulation, and optimization techniques to predict and optimize the set of input process parameters. Lastly, challenges and conclusions of the MAF process are presented.

“…Thus, the as-built parts usually demand posttreatment like heat treatment, hot isostatic pressure, and surface modification [26,27]. Among them, heat treatment is a cost-effective process to modify microstructure heterogeneity and eliminate defects that are intrinsically induced by rapid solidification or layer-wise building process [28,29]. Qi et al [30] investigated the influences of heat treatment on the microstructure of Al-based alloy prepared using PBF-LB and found that high-density needle-like ultrafine Al 2 CuMg precipitates presented after artificial aging, which significantly improved the yield strength.…”

Magnesium (Mg) alloys are considered to be a new generation of revolutionary medical metals. Laser-beam powder bed fusion (PBF-LB) is suitable for fabricating metal implant with personalized and complicated structure. However, the as-built part usually exhibits undesirable microstructure and unsatisfied performance. In this work, WE43 parts were firstly fabricated by PBF-LB and then subjected to heat treatment. Although high densification rate of 99.91% was achieved using suitable processes, the as-built parts exhibited anisotropic and layered microstructure with heterogeneously precipitated Nd-rich intermetallic. After heat treatment, fine and nano-scaled Mg24Y5 particles were precipitated. Meanwhile, the α-Mg grains undergone recrystallization and turned coarsened slightly, which effectively weakened the texture intensity and reduced the anisotropy. As a consequence, the YS and UTS were significantly improved to 250.2 ± 3.5 MPa and 312 ± 3.7 MPa, respectively, while the elongation still maintained at high level of 15.2%. Furthermore, the homogenized microstructure reduced the tendency of localized corrosion, and promoted the development of uniform passivation film. Thus, the degradation rate of WE43 parts was reduced by an order of magnitude. Besides, in-vitro cell experiments proved its favorable biocompatibility.
