“…As several businesses aim to exploit these emerging design possibilities, it is crucial to conduct comprehensive examinations of the microstructure and characteristics of additively made materials in different scenarios, including both ambient and increased temperatures [1]. Throughout history, there has been a significant amount of research conducted on material characteristics and microstructures within the realm of conventional production methods [2]. Nevertheless, the distinctive method of layerby-layer deposition employed in additive manufacturing presents novel intricacies and potentialities for material characteristics.…”

The utilisation of additive manufacturing (AM) has brought about a significant transformation in the manufacturing process of materials and components, since it allows for the creation of complex geometries and customised designs. The primary objective of this study is to conduct a thorough analysis of the microstructure and characteristics of materials produced by additive manufacturing techniques, including the effects of varying temperatures ranging from ambient temperature to increased levels. Microstructural analysis encompasses several methods, including optical microscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD), which are employed to investigate the grain structure, porosity, and phase composition. Standardised testing procedures are employed to assess mechanical qualities, such as tensile strength, hardness, and fracture toughness. temperature analysis methods, such as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), are utilised in order to examine the temperature stability and phase transitions. This study investigates the impact of various printing factors, including layer thickness, printing speed, and build orientation, on the resultant microstructure and characteristics. This study aims to address the disparity between theoretical understanding and actual implementation, therefore facilitating the wider use of additively made materials in businesses that need exceptional performance in many environments.

“…The study will utilise sophisticated microscopy methodologies to precisely analyse the temporal changes in the microstructure of the alloy, both under ambient conditions and at increased temperatures. Concurrently, the utilisation of mechanical testing techniques will yield valuable insights into the alloy's behaviour in the face of temperature fluctuations, therefore illuminating the alterations in its tensile strength, hardness, and resilience [9]. Through the pursuit of these aims, our aim is to make a valuable contribution to the wider comprehension of material behaviour in situations characterised by elevated temperatures.…”

This research investigates the microstructural characteristics and mechanical properties of a high-temperature superalloy under different temperature settings. The objective of this study is to analyse the alloy’s reaction to thermal stress, with a specific focus on both room and increased temperatures. By employing sophisticated microscopy techniques, researchers are able to closely examine the development of microstructural characteristics, which provides valuable understanding of phase changes and the dynamics of grains. Simultaneously, evaluations of mechanical properties, including tensile strength, hardness, and resilience, offer a holistic comprehension of the alloy’s operational characteristics. This research enhances the overall understanding of the alloy’s appropriateness for high-temperature applications by considering a wide range of temperatures. The results not only contribute to our fundamental understanding of materials science but also have ramifications for the development of alloys that can endure severe heat conditions.
