查询词典 cracking

When Ts is 850 ℃,grains are fined and the size of βphase and the distance betweenβphase pasticles are small.The corrosion barrier effect ofβ phase onαphase is enhanced and the iron content does not increase much at this temperature.So the corrosion resistance is improved.The corrosion resistance of AZ70 alloy falls off when Ts is 890 ℃,which attributes to the presence of microporosity,hot cracking and increase of iron content.

过热温度为810 ℃时，热速处理对合金耐腐蚀性能的改善作用并不大；过热温度为850 ℃时，热速处理显著细化了合金晶粒，β相的尺寸和间距变小，β相对α相腐蚀的阻碍作用增加，而且合金中的铁含量并没有提高，从而改善了合金在试验条件下的耐腐蚀性能；过热温度为890 ℃时，组织中存在热裂纹和显微疏松缺陷，合金含铁量显著增高，合金的耐腐蚀性能下降。
