Microstructure of the Exploded Graphites in Cast Iron
-
摘要: 用透射電子顯微鏡和掃描電鏡研究了鑄鐵中開花狀石墨的微觀結構,結果表明,開花狀石墨是石墨沿[0001]方向生長速率增大的過程。因而它是1種過球化石墨,而不是鑄鐵過程中球化不良造成的。Abstract: The microstructure of the exploded graphites in cast iron were investigated by using Transmission Electron Microscope and Scanning Electron Microscope. Experimen-tal results show that the exploded graphite is the process in which the growth of the graphite increased. So it does not result from poor nodulizing during the melting of cast iron, but is a kind of graphite with excess nodulizing.
