Following a scan of the temperature dependence of coercivity, two annealing temperatures of 420 °C and 650 °C yield higher coercivity, but via different mechanisms. 420 °C annealing facilitates the formation of the REFe₂ phase, and partially thickened grain boundary (GB). 650 °C annealing results in the decomposition of the REFe₂ phase, and its re-formation during furnace cooling. In fact, comparing cooling from 650 °C via water-quenching, air-cooling, and furnace-cooling demonstrates that the latter (slowest) cooling rate yields the maximum REFe₂ phase fraction of 5.4 wt.%. Significantly, the formation of this REFe₂ phase is accompanied by the expulsion of Ce from RE₂Fe₁₄B matrix shell, and the concomitant infiltration of Nd into the RE₂Fe₁₄B matrix shell. As a result, a maximum compositional difference between Nd and Ce in the RE₂Fe₁₄B matrix shell is recorded in the 650 °C furnace-cooled sample ([Nd]_shell – [Ce]_shell = 7.1 wt.%), yielding a maximum coercivity of 12.6 kOe.

The results show that both steels are subjected to dissolution corrosion with LBE preferentially attacking defective areas. The average dissolution depths of “LPBF 316L” steel are much larger than those of “LPBF+HIP 316L” steel, suggesting that the nonequilibrium defects generated by LPBF significantly exacerbate dissolution corrosion, whereas dissolution resistance recovers following HIP treatment. The dissolution zones invariably undergo austenite-to-ferrite phase transformation. Kurdjumov-Sachs (K-S) and Nishiyama-Wassermann (N-W) are the predominant orientation relationships (ORs) of <em>α</em> and <em>γ</em> phases, especially in “LPBF+HIP 316L” steel. While Pitsch OR is also identified, it constitutes only a small fraction. Atomic-resolution characterization reveals that at the penetration tips along mechanical nanotwin boundaries, a one-nanometer-thick, Bi- and Ni-rich, coherent interfacial phase forms at the interface between steel matrix and a nanosized amorphous oxide scale, mediating the leaching of Ni. Theoretical computations confirm that Bi is energetically more favorable than Pb in segregating on austenitic steel surfaces. The interfacial segregation of Bi facilitates the outer diffusion of Ni due to the negative enthalpy of mixing of the Ni-Bi system. Fe and Cr are also extracted through oxidation/decomposition processes. Consequently, the dissolution process involves simultaneous removal of all three steel elements, rather than just Ni.
