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.
T73和RRA时效处理改善了合金晶界特性，有助于阻止氢脆、减缓晶界阳极溶解速度，提高合金的抗应力腐蚀能力。
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.
实验结果表明：进行调质预处理是防止氢脆失效较为有效的方法。
