Yttrium is used to increase the strength of aluminium and magnesium alloys. [15] The addition of yttrium to alloys generally improves workability, adds resistance to high-temperature recrystallization, and significantly enhances resistance to high-temperature oxidation (see graphite nodule discussion below).
Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation.
Explore the comprehensive guide on yttrium, a transition metal with a wide range of applications in modern technology and medicine. Discover its history, physical and chemical properties, as well as its uses in industries like electronics, healthcare, and aerospace.
2 dni temu · The effects of yttrium additions (Y) addition (0–0.12%) on the microstructure and mechanical properties of a Sr-modified Al–Si–Mg alloy were systematically investigated. The results reveal that the addition of Y results in refinement of the α-Al dendrite and eutectic Si, and promotes the fibrous structure transformation of eutectic Si. New phases Al3Y and Y2Al3Si2 were precipitated in ...
3 kwi 2019 · The evolution of microstructure and mechanical properties are analyzed by comparing the alloys with different concentration of yttrium. The results show that most of yttrium atoms are solved at the roots of secondary dendrite arms as during directional solidification.
1 sty 2023 · The effects of yttrium (Y) addition on the microstructure and high-temperature mechanical properties of Inconel 718 have been investigated. Alloys containing a range of Y (0–0.58 wt%) were fabricated using selective laser melting, followed by solution and aging heat treatment.
Yttrium is often used in alloys, increasing the strength of aluminum and magnesium alloys. It is also used as a deoxidizer for non-ferrous metals such as vanadium . Yttrium is used as a catalyst in ethylene polymerization.
