JOURNAL OF ALLOYS AND COMPOUNDS, ISSN: 0925-8388, No.181777, pp.1-16, 2025 Streszczenie:
In this study, Haynes 282 alloy bars were fabricated using Direct Metal Laser Sintering (DMLS) in three build orientations: 0°, 45°, and 90°. The process was conducted under an argon protective atmosphere with an energy density of 104 J/mm³, a laser power of 100 W, and a scanning speed of 800 mm/s. The additively manufactured (AM) specimens underwent fatigue testing at stress amplitudes ranging from ±550 MPa to ±800 MPa. Specimens printed at 0° and 45° showed significantly improved mechanical performance, indicating these orientations are more favorable. Notably, the AM specimens demonstrated extended service life at stress amplitudes below 700 MPa, highlighting the potential of DMLS for producing durable Haynes 282 components. Słowa kluczowe:
