未经扩氢退火的电渣钢大锻件经超声波检验，未发现白点缺陷。
Ultrasonic testing shows on flake defects in theheavy forgings of ESR steel without any diffusion annealing.
导致氢含量过高的原因可能在于锻后退火不足。
The main rason of leading to overhigh hydrogen content was insufficient anneal after forged.
此外，随着退火温度的提高，氢渗透时间和氢陷阱系数也增大，而氢的扩散系数则降低。
In addition, both hydrogen permeation time and trapping coefficient of hydrogen increase but the hydrogen diffusivity decreases in the steel with the elevation of annealing temperature.
