Title:
HYDROGEN EMBRITTLEMENT PREVENTION AGENT FOR ALUMINUM ALLOY MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/270483
Kind Code:
A1
Abstract:
This hydrogen embrittlement prevention agent for an aluminum alloy material can prevent hydrogen embrittlement in an aluminum alloy material, and is for a use in which the hydrogen embrittlement prevention agent is included as second phase particles in the interior of an aluminum alloy material. The second phase particles include at least one type of particles among Sn particles, Al11Mn3Zn2 particles, Al9Co2 particles, Al6Mn particles, Al3Y particles, Al3Ti particles, Al3Sc particles, Al2Ca particles, Al7Cr particles, Al9Mn4 particles, Al12Mn3Si particles, and Al31Mn6Cu2 particles. This hydrogen embrittlement prevention agent for an aluminum alloy material can effectively prevent or suppress hydrogen embrittlement.
