ASTM F75 Alloys: A Systematic Review of Microstructural Characteristics and Manufacturing Advances from Conventional to Laser-Based Techniques with Bibliometric Analysis
Keywords:
Additive manufacturing, ASTM F75 alloys, Laser powder bed fusion, Microstructural characterization, Mechanical propertiesAbstract
This study provides a systematic and bibliometric review of
ASTM F75 cobalt–chromium alloys, focusing on
microstructure and the shift from conventional to laserbased manufacturing. Using combined analytical methods, it
evaluates microstructure, mechanical properties, corrosion
behavior, and biocompatibility. Results show that laserbased techniques such as LPBF and DMLS produce finer grain
sizes (1–10 µm vs. 50–200 µm), leading to improved hardness
(20–40%) and tensile strength (15–30%). Despite challenges
like residual stress and process optimization, these methods
show strong potential for high-performance and sustainable
applications.
