Abstract
Additive manufacturing Fe-Mn-Si-Cr-Ni alloys exhibit promising potential to replace traditional Cr-Ni stainless steels in applications requiring corrosion resistance and wear resistance. In this work, five types of Fe-17Mn-6Si-9Cr-5Ni alloys with varying B content (0-0.5 wt.%) were fabricated via laser metal deposition, and their wear resistance under oil-lubricated conditions was investigated. Results showed that the alloy with 0.5 wt.% B addition possesses the best wear resistance, which volumetric wear rate reduced to 19.4% of that of the B-free alloy. The analysis revealed that the enhancement of wear resistance in additive manufacturing Fe-Mn-Si-Cr-Ni alloys due to B addition is not only attributed to increased hardness, but also extends to the promotion of friction-reducing and anti-wear characteristics inherent to Fe-Mn-Si-Cr-Ni alloys.
期刊介绍：
ASM International''s Journal of Materials Engineering and Performance focuses on solving day-to-day engineering challenges, particularly those involving components for larger systems. The journal presents a clear understanding of relationships between materials selection, processing, applications and performance.
The Journal of Materials Engineering covers all aspects of materials selection, design, processing, characterization and evaluation, including how to improve materials properties through processes and process control of casting, forming, heat treating, surface modification and coating, and fabrication.
Testing and characterization (including mechanical and physical tests, NDE, metallography, failure analysis, corrosion resistance, chemical analysis, surface characterization, and microanalysis of surfaces, features and fractures), and industrial performance measurement are also covered
