Crystallographic character of grain boundaries resistant to hydrogen-assisted fracture in Ni-base alloy 725

Crystallographic character of grain boundaries resistant to hydrogen-assisted fracture in Ni-base alloy 725

Exactly how hydrogen renders metals brittle is still unclear, and it remains a challenge to predict component failure due to hydrogen embrittlement. Here, the authors identify a class of grain boundaries in a nickel superalloy that deflects propagating cracks and improves alloy resistance to hydroge...
