Corrosion and Protection of High-Strength Aerospace Aluminum Alloys

Abstract

Exploring corrosion mechanisms and developing new protective methods are essential to avoid the failure induced by corrosion for aluminum alloys. Methods to improve service stability of aerospace aluminum alloys were discussed.

Advances in Ag2Se-based thermoelectrics from materials to applications

“…Benefiting from these advanced strategies and newly developed concepts, high ZT values have been achieved in a broader range of thermoelectric materials. 27,28 For instance, some thermoelectric materials have achieved ZT values of 41, such as SnTe, [29][30][31] Mg 2 Si, 32,33 SiGe, 34,35 clathrates, 36,37 half-Heusler, [38][39][40] MgAgSb, [41][42][43] Mg 3 -(Sb/Bi) 2 , 44,45 and skutterudites. [46][47][48] Some state-of-the-art thermoelectric materials have even been reported to have high ZT values of 42, such as SnSe, [49][50][51][52][53][54] Cu 2 Se, [55][56][57] GeTe, [58][59][60] and PbTe.…”
