Yonguk Lee recently published “On the Formation of Multiply Coherent γ Grains in a Powder Metallurgy Ni Base Superalloy” in the Superalloys 2024 proceedings. The paper reports a unique γ microstructure which contains multiple pinning particles inside that are coherent (multiply coherent gamma grains,… Read More
