Switching nanoprecipitates to resist hydrogen embrittlement in high-strength aluminum alloys

HIGHLIGHTS

  • who: Yafei Wang from the (UNIVERSITY) have published the article: Switching nanoprecipitates to resist hydrogen embrittlement in high-strength aluminum alloys, in the Journal: (JOURNAL) of 21/04/2022
  • what: The authors show that hydrogen embrittlement of aluminum alloys can be largely suppressed by switching nanoprecipitates from the u03b7 phase to the T phase without changing the overall chemical composition. The authors show that nanosized age-hardening precipitates, widely available and serving as core-strengthening elements in high-strength aluminum alloys, can be switched into strong hydrogen trap sites and contribute to elevated HE resistance . . .
