1Effects of slope plate variable and reheating on semi-solid structure of ductile cast iron显示文摘Semi-solid metal casting and forming are known as a promising process for a wide range of metalalloys production. In spite of growing application of semi-solid processed light alloys, a few works have been reportedabout semi-solid processing of iron and steel. In this research inclined plate was used to change dendritic structureof iron to globular one. The effects of length and slope of plate on the casting structure were examined. The resultsshow that the process can effectively change the dendritic structure to globular. In the slope plate angle of 7.5? andlength of 560 mm with cooling rate of 67K·s-1 the optimum nodular graphite and solid globular particle were achieved.The results also show that by using slope plate inoculant fading can be prevented more easily since the total time ofprocess is rather short. In addition, the semi-solid ductile cast iron prepared by inclined plate method, was reheated to examine the effectof reheating conditions on the microstructure and coarsening kinetics of the alloy. Solid fraction at different reheatingtemperatures and holding time was obtained and based on these results the optimum reheating temperature rangewas determined.M. Nili-Ahmadabadi F. Pahlevani P.

2Effect of Slope Plate Variable and Reheating on the Semi-Solid Structure of Ductile Cast Iron显示文摘Semi-solid metal casting and forming is a promising production method for a wide range of metal alloys. In spite of many applications for semi-solid processed light alloys, few works have reported on the semi-solid processing of iron and steel. In this research, an inclined plate was used to change the dendritic structure of iron to globular. The effects of the length and slope of the plate on the casting structure were examined. The results show that the process effectively changes the dendritic structure to globular. A sloped plate angle of 7.5° and length of 560 mm with a cooling rate of 67 K·s-1 gave the optimum graphite nodu- larity and solid particle globularity. The results also show that the sloped plate more easily prevents inocu- lant fading since the total time processing is rather short. In addition the semi-solid ductile cast iron prepared using the inclined plate method was reheated to examine the effect of reheating conditions on the micro- structure and coarsening kinetics of the alloy. The solid fractions at different reheating temperatures and holding times were used to find the optimum reheating temperature range.M. Nili-Ahmadabadi F. Pahlevani P.
