The formation of the icosahedral phase (I-phase) as a secondary solidification phase in Mg-Zn-Y and Mg-Zn-Al base systems provides useful advantages in designing high performance wrought magnesium alloys. The strengthening in two-phase composites (I-phase + α-Mg) can be explained by dispersion hardening due to the presence of I-phase particles and by the strong bonding property at the I-phase/m...

The influence of heat treatment time and temperature on the microstructure and corrosion resistance of cast stainless steel alloys CN3MN (UNS J94651) and CK3MCuN (UNS J93254) were investigated with a combination of microscopy techniques and immersion corrosion testing. The as-cast alloys exhibited significant residual microsegregation of Mo across the dendritic substructure and the presence of ...

High strength, wrought 7xxx (Al-Zn-Mg) and Al-Li based alloys show a propensity for fatigue macroscopic crack deflections aligned along grain boundaries. The present work reports a study on a 3 rd generation Al-Li based alloy in the form of a thick AA2297 (Al-Cu-Li alloy) plate, where it was found that although the lithium containing material may indeed be more susceptible to mixed mode grain b...

Abstract Aluminum scrap is often contaminated with steel parts, leading to accumulation of Fe in recycled Al alloys. Consequently, low limits for wrought alloys are difficult meet by recycling without dilution primary Al. Wrought a higher tolerance could help overcome this problem and improve the sustainability products. Here we study effects increasing content EN AW-6060, 6005A, 6082 from 0.2 ...

TITANIUM is a low-density element (approximately 60% of the density of steel and superalloys) that can be strengthened greatly by alloying and deformation processing. (Characteristic properties of elemental titanium are given in Table 2.1.) Titanium is nonmagnetic and has good heat-transfer properties. Its coefficient of thermal expansion is somewhat lower than that of steel and less than half ...

Compared with pure aluminum and wrought alloys, Al foundry alloys are more difficult to be anodized. The high content of alloying elements prevents the uniform growth oxide layer enhances embedding defects in anodic film. microstructure substrate anodizing parameters play a key role final quality layer. Variations chemical composition, casting process, pre‐ post‐anodizing treatments can signifi...
