The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but

Iron deficient anemia is a decreased total iron body content. It occurs when iron deficiency is severe enough to lower the amount of red blood cells being formed and it causes the development of anemia. It is the most common deficiency in the world. Hemorrhages can also cause anemia and much greater problems. Bleeding can also be so slow that it is often overlooked. Iron is a necessity for all living organisms because it is needed for many processes. Iron levels are carefully regulated by

A Case of Iron Deficiency (Summarizing and Note-Taking) Describe the structure of a molecule of hemoglobin and explain the role played by iron in the transport of oxygen. The structure of hemoglobin is a hemi group. A hemi group consists of an iron (Fe) ion held in a heterocyclic ring. Iron binds with oxygen. Therefore‚ it has a very important role in transporting oxygen in the blood. How is iron stored and transported in the body? Iron can be stored within intestinal entrecotes bound to ferritin

IRON (METAL) Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole‚ forming much of Earth’s outer and inner core. It is the fourth most common element in the Earth’s crust. Iron’s very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars‚ Like other group 8 elements‚ iron

Ashland County West Holmes Career Center Mrs. Bender 1 Background Iron powder will react with cupric sulfate in a onetoone ratio (1 mole to 1 mole). The students will also be able to more easily visualize the size of a mole of iron and copper. The result obtained in this lab usually have less than a one percent error. Fe(s) + CuSO4 (aq) > FeSO4(aq) + Cu(s) Iron powder cupric sulfate ferrous sulfate copper In the reaction‚ iron will be the limiting reagent; it will be completely used up in the reaction

In Support of Israel’s Iron Dome Since the beginning of time Israel has been disputed land. Israel has been disputed by many ethnicities since before Christ. The Christians‚ Muslims‚ and Jews have ruled parts of Israel‚ and today the Jews rule once again.

------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those
