采用厚度近似等于平均晶粒度的薄板316不锈钢试件，研究了晶界特征和几何角度对晶间应力腐蚀开裂(IGSCC)启裂倾向的影响。低Σ级碳纤维尤其是Σ-3级碳纤维具有较高的抗裂变性能。GB的裂纹萌生敏感性随GB倾角α的减小而增大。施加在GB上的净等效法向应力(Δ*σN)随着两侧颗粒间施密德因子失配(Δm)的增大而增大。结果表明，Δ*σN最初随ΔmWhen 0≤Δm≤0.0 4时略有增加，然后随ΔmWhen 0.0 4和Δm≤0.18急剧增加。提出了一种预测国标综合指数的标准，结果表明，Δ*σ不超过0.06的国标的综合国标指数较高。
The dependence of intergranular stress corrosion cracking (IGSCC) initiation propensity on the grain boundary (GB) characters and geometrical angles was investigated by utilizing a thin sheet 316 stainless steel sample, of which the thickness was approximately equal to the average grain diameter. The low-ΣCSL GBs especially theΣ3 GBs had higher resistance to cracking initiation. The cracking initiation susceptibility (CIS) of a GB increased with the decrease in the GB inclination angleα. The net effective normal stress (Δ*σN) exerted on a GB increased with the Schmid factor mismatch (Δm) between the two-side grains. It was found that theΔ*σNinitially slightly increased withΔmwhen 0≤Δm≤0.04, and then steeply increased withΔmwhen 0.04<Δm≤0.18. A criterion was proposed to predict the CIS of a GB, which demonstrated that the CIS of a GB with theΔ*σNover 0.06 would be high.
