Analysis of Phase Transformations and Structural Properties in Stainless Steel 316L Powder

Using X-Ray Diffraction (XRD), this research characterized phase contents and structural validity of SS316L stainless steel powder. SS316L features enhanced corrosion resistance, mechanical strength, and heat tolerance making it a universal selection across challenging environments. XRD identified SS316L powder crystallographic structure and also identified any unwanted secondary phases that may negatively impact its capability to function in actual world applications.The XRD pattern of the powder included 3 distinct peaks at 2θ = 43.5°, 50.6°, and 74.6° for the (111), (200), and (220) planes of a face centered cubic (FCC) crystal structure indicating it is in the austenitic phase (γ-Fe). The three distinctive peaks likewise imply no undesirable secondary phases (ferrite, sigma phase, or chromium carbides) existed meaning high structural integrity in the powder.The structural integrity of the SS316L powder is vital, considering its value addition in the form of corrosion resistance, mechanical stability over a wide service performance, and performance dependability for use in applications such as; biomedical implants and aerospace parts. XRD results support the SS316L powder can and will work for additive manufacturing, and other high-performance fabrication performance-based processes wherein structural integrity is the priority. Thus, XRD analysis offers itself as a useful tool for verification of powder phases and quality control for high performance engineering metal powders as additive manufacturing increases in popularity.
