  1. For the manifold of sedan engine, the hest thermal fatigue properties can be obtained by keeping the percent of vermicular graphite at about 50 %, therefore it shouldn ' t he considered that the lowest e. g. percent limit of 50 % specified in chinese vermicular iron standard is too lower, and it is also not proper to take the v. g. percent as the basis for judging the level of production technology

    摘要對轎車發動機排氣歧管而言,蠕化率控制在50 %左右可以獲得最佳的抗熱疲勞性能,因此不能認為我國的蠕鐵標準中規定的蠕化率高於50 %的要求偏低了,也不能把蠕化率的高低作為衡量工藝水平的依據。
  2. Dry sliding friction characteristics of vermicular graphite iron

    高速干滑動下材料摩擦學性能的研究進展
  3. The fracture toughness values of vermicular graphite cast iron specimen subjected to four different heat treatment methods were tested and compared

    摘要比較四種熱處理方法下蠕墨鑄鐵試樣的斷裂韌度。
  4. How to control and check percentage of vermicular graphite was described, and some suggestions to prevent vermicularizing effect degeneration were offered

    介紹如何控制、檢測蠕化率,並對如何防止蠕化衰退提出建議。
  5. The influences of furnace charges, chemical composition, quality of vermicularizing alloy, holding duration after vermicularizing treatment and tapping temperature on percentage of vermicular graphite were discussed

    摘要討論爐料、化學成分、蠕化劑質量、處理后包內保留時間和溫度對蠕墨鑄鐵蠕化率的影響。
  6. The metamorphous graphite in the section center of heavy section s. g. iron castings is superspheroidal graphite, and not the product of degeneration along the direction from shperoidal graphite to vermicular or flake graphite

    大斷面鑄件中心的變態石墨是過球化石墨,而不是球狀石墨向蠕蟲狀石墨或片狀石墨方向衰退的產物。
  7. The results indicate that the fracture toughness is influenced markedly by the different base structure of vermicular east iron and by the form of graphite ; unlike steel, the fracture toughness of vermicular cast iron increases with the yielding strength, while drops drastically with the increase of ratio of graphite grain length to thickness

    試驗結果表明,蠕墨鑄鐵的斷裂韌度受不同基體組織的影響比較明顯;受不同石墨形態的影響顯著,與結構鋼不同,蠕墨鑄鐵的斷裂韌度隨材料的屈服強度增大而增大,隨石墨顆粒的長厚比增加會急劇下降。
