It has been known for decades that the application of pulsed direct current can significantly
enhance the formability of metals. However, the detailed mechanisms of this effect have …

The dissolution, refinement, and separation of the particles are one of the core metallurgical
processes to control the quality of metallic materials. The dimensional changes and …

Duplex stainless steels suffer from thermal aging embrittlement that results from severe
phase decomposition in ferrite phase after a long-term service at temperatures of 550–700 …

The homogenization heat treatment is a key procedure to controlling the second phase,
enhancing composition uniformity and workability of as-cast Cu–15Ni–8Sn alloy …

Precipitation of copper-rich nanoclusters is the chief culprit, which is the cause of
embrittlement of reactor pressure vessels. Here we provide a real sense of``in situ''pathway …

During the solidification of superalloy, dendrite segregation will be inevitably formed,
causing uneven structure and performance. Segregation elimination and atomic diffusion in …

The traditional solution (1120° C/4 h) and aging (845-1080° C/24 h) processes are the keys
for K417G superalloy to obtain the expected microstructure and ensure excellent …

The second phases at grain boundaries including block-shaped long-period stacking
ordered (LPSO) phases and bright W phases are the chief culprits damage the deformability …

Conventional kinetics theory for diffusion-controlled phase transformation shows that the
reverse transition should lag behind the temperature rise through rapid heating, ie …

Secondary aluminum has received extensive attention due to its low energy consumption,
low emissions, and good recyclability; however, the high impurity iron content in secondary …
