Solidification and modeling of cast iron—A short history of the defining moments
Human civilization has evolved from the Stone Age, through the Bronze Age to reach the Iron Age around 1500 B.C. There are many to contend that today we are living in the age of engineered materials, yet the importance of iron castings continues to support the thesis that we are still in the Iron Age. Cast iron, the first man-made composite, is at least 2500 years old. It remains the most impor...
متن کاملOn the Effect of Pouring Temperature on Spheroidal Graphite Cast Iron Solidification
This work is focused on the effect of pouring temperature on the thermal-microstructural response of an eutectic spheroidal graphite cast iron (SGCI). To this end, experiments as well as numerical simulations were carried out. Solidification tests in a wedge-like part were cast at two different pouring temperatures. Five specific locations exhibiting distinct cooling rates along the sample were...
متن کاملCooling rate optimization of as-cast consciously cast steel
Abstract: A combination of a finite element method (FEM) algorithm with ANSYS codes and post image processing of NDT ultrasonic images along with laboratory cooling experiments and microstructural analysis provide a guideline to determine the optimum cooling rate for any grade of steel in which the highest productivity can be achieved without any degradation of the cast steel products. The sugg...
متن کاملROLE OF SiCp ON THE SOLIDIFICATION RATE AND FORGEABILITY OF STIR CAST LM6/SiCp MMCs
The present paper aims to investigate the solidification behavior and the forgeability of Aluminum alloy (LM6)-SiCp composites at different section of three-stepped composite castings. The temperature of the cast composites during solidification has measured by putting K-type thermocouples at the center of the each step/section, from which the solidification curves were constructed. The forgeab...
متن کاملSolidification Phenomena and Properties of Some Cast Tool Steels
The freezing process. microstructures and phase relationships in some experimental cast tool steels have been investigated and developed under the various solidification conditions. Experimental steels were based on AISI M2 and M10 grades high speed steels. Addition of carbide forming elements such as niobium and titanium with and without extra carbon were made to the molten bath of the base st...
