“…They also emphasized that modulation of particle size was significant for sake of controlling and designing the ideal microstructures [77]. Furthermore, in order to obtain the refined microstructure of thin-wall, auxiliary methods, such as ultrasonic vibration (UV), magnetic field, and electric -magnetic coupled field, were chosen to modify the microstructure [78][79][80][81]. Liu et al deposited the Fe 60 on the Q 235 steel with the auxiliary of rotating magnetic field and obtained smaller grain size compared to that without the magnetic field owing to the existing of electromagnetic stirring which contributed to the breaking of columnar crystal and creating of crystal nucleus [79].…”

Owing to the versatility without expanding the machine’s size, thin-wall has been widely used in high-value parts. The investigation of laser additive manufacturing (LAM), which has advantages such as high powder density, easy controllability, and excellent stability, on the fabrication of thin-wall has drawn much attention. In this paper, the research status of macroscopic and microstructural features of metal thin-wall fabricated by LAM has been reviewed. The deposition quality was mainly focused on the effect of process parameters and especially the matching of z-increment and single deposition height. Based on the grain size and growth of columnar, the characteristics of microstructures were analyzed. Considering the structural feature of thin-wall, the effect of grain size and phases on the hardness and distribution of hardness were discussed. The effect of grain size, phases and loading direction on the tensile properties were reviewed. The distribution and modification of thermal stress were presented.

“…For instance, Liu et al cladded the Fe 60 on the Q 235 steel by rotating the magnetic field auxiliary laser cladding. The results indicated that the microstructure is refined, and the hardness of the coating increases about 10% compared with that deposited without magnetic filed [ 72 ]. Chen et al deposited the 304 coating on the #45 steel by the laser cladding with the auxiliary of an electric and magnetic coupled field.…”

The service life of rails would be remarkably reduced owing to the increase of axle load, which can induce the occurrence of damages such as cracks, collapse, fat edges, etc. Laser cladding, which can enhance the mechanical properties of the rail by creating a coating, has received great attention in the area of the rails due to the attractive advantages such as low input heat, small heat-affected zone, and small deformation. In this paper, recent developments in the microstructural characteristics and mechanical properties of a cladded layer on the rail are reviewed. The method of process optimization for enhancing the properties of a cladded layer are discussed. Finally, the trend of future development is forecasted.

( 14) Optimization of additive manufacturing processes, such as a magnetic approach, WAAM and HF-WAAM, can help improve the yield strength and ultimate tensile strength of rails [62][63][64][65]. [66] Fe-based martensitic stainless steel (MSS) The mechanical properties (e.g., tensile strength and residual stress) of laser cladded rail is affected by the material type, the granularity of alloy powders and 3D printing processes (e.g., scanning pattern, designed angle, printing speed and laser power) [37,38].…”

Additive manufacturing technologies, well known as three-dimensional printing (3DP) technologies, have been applied in many industrial fields, including aerospace, automobiles, shipbuilding, civil engineering and nuclear power. However, despite the high material utilization and the ability to rapidly construct complex shaped structures of 3D printing technologies, the application of additive manufacturing technologies in railway track infrastructure is still at the exploratory stage. This paper reviews the state-of-the-art research of additive manufacturing technologies related the railway track infrastructure and discusses the challenges and prospects of 3D printing technology in this area. The insights will not only help the development of 3D printing technologies into railway engineering but also enable smarter railway track component design and improve track performance and inspection strategies.
