A Fe-based filler material with the composition of Fe-20Ni-5Co-2.5Mn-0.2C was used for welding 9% Ni steel, and effect post-weld heat treatment on microstructure mechanical properties welded joints investigated. Post-weld joint performed in temperature range 200 to 600 ℃. After experimental selection, changes weld metal base were investigated detail at temperatures 350 Grain morphology, size, l...

For the additive manufacturing of chromium-oxide coated stainless steel powders, melting, diffusion, sintering behaviors cementite phase in during heat treatment can affect products’ physical and chemical properties, thus, are worth studying. In this work, we use ReaxFF reactive force-field-based molecular dynamics simulations to investigate at level through an atomistic-scale representation fo...
