1
The results show that the precipitates on the grain boundaries and precipitatefreezone (PFZ) were the main factor to enhance the intergranular crack of the alloy.
结果发现，时效造成的沿晶析出及伴随产生的沉淀物无析出带是促使合金发生沿晶开裂的主要因素。
2
The effect of aging treatment on corrosion sensitivity is closely related to S' phase, the phase precipitated in grain boundary and precipitate-freezone.
