Integrated Alloy Design And Additive Manufacturing Of Low-Density Fe-Mn-Al-Ni-Cr-C Steel: Gas Atomization, Laser Directed Energy Deposition, And Microstructure-Property Relationships
This study introduces a new low-density steel (LDS) with an austenitic matrix strengthened by a stable, finely dispersed B2 intermetallic phase to optimize strength and toughness. The alloy was produced through vacuum induction melting and casting, followed by gas atomization to create spherical powders suitable for ad...
