WELDING OF CAST IRON Cast iron is an extremely versatile material‚ used in thousands of industrial products. It is hard‚ wearresistant‚ and relatively inexpensive. Like steel‚ it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility)‚ this is not true of all cast irons‚ as we shall see shortly. Cast iron‚ like steel‚ is an iron-carbon alloy. In composition and structure‚ and in some of its properties‚ it is quite different

Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can

Is Our Constitution Still Relevant? The United States Constitution is often called “a miracle document” because it has proved so enduring while so many other attempts at self-government have failed. In reality‚ it was a miracle of sorts that the Constitutional Convention ever materialized in the first place. This is one of the reasons I believe the constitution is still relevant. The articles of confederation weren’t working so the constitutional convention was finally held in order to draft the
