Superior Shock Resistance of Magnesium and Magnesium–Aluminum Alloys with Cerium Addition

Advanced Engineering Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 28, 2025

This study investigates the shock response of forged and annealed commercially pure magnesium (Cp – Mg) its cerium (Ce)‐alloyed variants (Mg 0.5Ce Mg 3Al 0.5Ce). Shock loading is performed using a conventional tube setup at two pressure levels along forging direction (FD). Under low‐pressure conditions, all materials deform without fracturing, with Cp exhibiting highest deflection. However, higher pressure, discs fracture, displaying brittle cleavage, whereas absorb impact energy failure due to their superior strength–ductility balance. Among Ce‐alloyed variants, demonstrates slightly better resistance, lower deflection effective strain. does not alter grain size but results in high density predominantly extension twins that complements slip activity materials, particularly pressures Mg. Post‐shock analysis reveals greatest reduction basal texture intensity Mg, while show moderate decrease. attributed twinning, twinning activity. Local misorientation indicates strain localization stress concentrations twin–matrix interfaces. Overall, exhibit resistance compared owing toughness, twin density, increased non‐basal

Study on the influence of process parameters on forming accuracy in hot incremental forming of 5A03 aluminum alloy

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

Aluminum alloys are widely used in various fields due to their excellent material properties, but the forming of aerospace small-batch aluminum thin-walled structures at room temperature often faces challenges such as cracking, poor accuracy, or even failure. This study combines incremental process with thermal-assisted techniques effectively improve accuracy alloy materials, thereby meeting needs for and customized product manufacturing. In thermal forming, is subjected complex multi-field coupling, including force field, structural leading highly deformation behavior. Therefore, by combining macroscopic microscopic approaches, this investigates influence different parameters on 5A03 pyramid-shaped components analyzes impact microstructure alloy, identifying optimal parameter combination superior accuracy.

The Dual Role of Twinning Deformation in a Magnesium Alloy up to Very High Cycle Fatigue Regime

Fatigue & Fracture of Engineering Materials & Structures, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

ABSTRACT In this work, push–pull cyclic loading tests were conducted on a LA42 alloy up to the very high cycle regime understand effects of internal defects and microstructural damage fatigue mechanisms. The S – N curve shows bilinear pattern with crack initiation characterized by multiple sites, interior shrinkage connection, induced facet formation. It is found that apart from basal slip, twinning deformation played dual roles in initiation. Under larger plastic deformations, improved strain compatibility between adjacent grains relaxing matrix damage, most occurred at shrinkages. contrast, proliferated long life under low strains, which enhanced interaction dislocation slip twinning, promoting formation facets shear stress. varied magnesium suggest traditional limit does not exist during long‐term loading.
