T73 and RRA treatment improve the grain boundary character, which is help to inhibit hydrogen embrittlement and decrease anodic dissolution rate, then to improve the SCCR of the alloy.
However its annealing embrittlement is rather great after the crystallization treatment of amorphous strips, so that destruction rates are very high, and the extensive application range is limited.
但由于非晶带材经过晶化处理后脆性很大，破坏率很高，从而限制其应用范围。

The results of the experiment show that it is effective to prevent hydrogen embrittlement failure by hardening and tempering treatment.
