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 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...
متن کاملRapid Solidification of Polymeric Fibers
A thorough understanding of crystallization kinetics for rapid polymer solidification during the fiber spinning process is a route to maximizing fiber properties while increasing production speeds. We are using theoretical, computational, and experimental models to characterize the crystallization process at the molecular, microscopic, and macroscopic levels. Polymer dependent molecular descrip...
متن کاملCast Iron Metallurgy
Cast iron (CI) is one of the oldest materials in commercial use. It has excellent compressive strength and is commonly used for structures that require this property, as well as for water and sewer lines. This article explains CI metallurgy and why the understanding of this metallurgy is key to understanding other ferrous materials and alloys. The composition of cast iron (CI) varies significan...
