| Abstract Scope |
The ability to build reliable, lightweight structures for transportation applications hinges on developing alloys having high mechanical strength and resistance to hydrogen embrittlement (HE). Since both are opposing characteristics for most of the alloys, understanding the governing factors that affect HE is important. This aspect has been studied for AA 7050 alloy due to its widespread application in the transportation sector. The role of precipitates on the dislocation dynamics both in the absence and presence of hydrogen and the hydrogen evolution kinetics in 3.5 wt.% NaCl solution has been studied using complementary techniques. It is shown that mere coherency between the matrix and the precipitates in the grains does significantly affect the HE tendency of the alloy, even though such precipitates show higher hydrogen evolution kinetics and lower oxygen reduction kinetics. The study provides insights that can help develop HE resistant Al-alloys with high mechanical strength. |
