“…Stainless steel (316L) has a notable fracture toughness (KIC) of 50 MPa√m, hence highlighting its exceptional resistance to crack propagation. In contrast, the measurement of fracture toughness in polymers is less frequently conducted as a result of their non-linear characteristics [31]. The fracture toughness of ceramic alumina is measured at around 4 MPa√m, indicating its inherent brittleness.…”

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 addition of inoculant particles provided strengthening in the resulting deposits, with almost all revealing improved tensile strength at the cost of ductility [27,32,33]. For a wide range of alloy systems, the inoculant has been found to decompose to produce heterogeneous nucleation sites for grain refinement and strengthening of the resulting composite, such as boron nitride nano-tube strengthened Ti-6Al-4V fabricated by DED [33], VC x strengthened 316L stainless steel fabricated using Laser Powder Bed Fusion (L-PBF) [27], as well as WC 1-x [34] and SiC [35] reinforced IN718 fabricated by L-PBF.…”
