1.
By the manufacture instance of two drawing parts namely petrol cover and end cover, the reasons occurring drawing crack defect during manufacture are analyzed separately, the occurring of blue brittleness and hydrogen brittleness during drawing are introduced, as well as related solving and guarding steps are provided.
通过油盖及端盖两种拉伸件的加工实例,分别分析了其在生产中出现拉裂缺陷的原因,由此介绍了拉伸加工中蓝脆与氢脆的产生并分别提出了各自的解决及预防措施。

However, at the temperature about 230℃, the sensibilities to stress corrosion increase abruptly, blue brittleness occurs and the stress corrosion is increased.
通过对不同强度等级的汽轮机转子钢进行应力腐蚀试验,研究发现,转子钢在一般水介质中应力腐蚀敏感性很小,但在230℃附近应力腐蚀敏感性突然增加,这可能是发生了蓝脆,增加了应力腐蚀。
3.
30Cr2Ni4MoV and 30Cr2MoV steels presented blue brittleness near 230℃ and 180℃, respectively.
本文研究了核电汽轮机用钢蓝脆和应力腐蚀的交互作用,结果表明:这类中强度钢在水介质中的应力腐蚀敏感性很小,只能用慢拉伸方法才能发现。
补充资料:景泰蓝点蓝
景泰蓝点蓝 景泰蓝主要制作工序之一。掐好丝的胎体,经烧焊、酸洗、平活、正丝后。便进入点蓝工序。其法用蓝鎗(金属小铲子)把碾细了的釉色填入丝工空隙处,经过800度火烧。如此反复三次到四次才完成。解放前,景泰蓝点色呆板单调,解放后,运用渲染、罩染、烘染、衬染、剔染等等技法,扩大了景泰蓝点蓝艺术的表现力。为表现形态多变的云、水,雾,以及水中倒影,点蓝艺人们和掐丝艺人共同创造了无丝点晕技法。即掐出高矮不同的丝工,点晕以不同釉色,使这些釉色自然的连接,经烧结后高丝露出,矮丝含在釉下,增强了铜胎和釉色的密着力。使其图案纹样更为丰富多彩。
