Influence of thermomechanical processing on coarse particles, grain structure, and mechanical properties of Al–Cu alloy rings

open access: yesJournal of Materials Research and Technology, 2023
Rings made of 2219 Al alloy are typically manufactured by multi-directional forging (MDF) and ring rolling at 460 °C, followed by heat treatment. However, this process often results in coarse elongated grains and a large number of coarse Al2Cu particles,

Effect of multi-pass multi-directional forging on tribological properties of Si-rich eutectoid ZA alloys

open access: yesTransactions of Nonferrous Metals Society of China, 2021
Abstract The effect of multi-pass multi-directional forge (MDF) on the tribological properties of ZA22−xSi alloy (x=0, 4, 8 wt.%) was investigated. The results indicate that MDF breaks down the cast microstructure of alloys and produces a well-modified microstructure comprising finely distributed α- and η-phases and primary Si particles.
