Iron iron carbide phase diagram. (b) In Iron-Carbon phase diagram, we can see that the maximum concentration of Carbon is 6.67%. This is due to the fact that maximum solubity of carbon in iron is 6.67% as it forms iron carbide (Fe3C form). After 6.67 percentage,there is no applicati… View the full answer Jun 1, 2012 — Iron-carbon phase diagram describes the iron-carbon system of alloys containing up to 6.67% of carbon, discloses the phases compositions and ...

The diagram shows iron ... 1660s, cast iron, from iron (n.) + cast (adj.) "made by melting and being left to harden in a mold" (1530s), past-participle adjective from cast (v.) in its sense "to throw something (in a particular way)," c. 1300, especially "form metal into a shape by pouring it molten" (1510s). From 1690s as an adjective, "made of cast-iron;" figurative sense of "inflexible, unyielding" is from 1830.
In the figure, there is the iron–iron carbide (Fe–Fe3C) phase diagram. The percentage of carbon present and the temperature define the phase of the iron carbon alloy and therefore its physical characteristics and mechanical properties. The percentage of carbon determines the type of the ferrous alloy: iron, steel or cast iron.

Binary phase diagram If a system consists of two components, equilibrium of phases exist is depicted by binary phase diagram. For most systems, pressure is constant, thus independently variable parameters are –temperature and composition. Two components can be either two metals (Cu and Ni), or a Hello engineers I have ASTM A500 grade B steel tubing that is being heated with a torch enough to bend it and I'm wondering how it will affect it's microstructure, yield point and ultimate tensile strength. I assume this will correlate with how hot the tubing gets. Therefore, my attention is at phase diagrams. From Matweb I am getting these values for the chemical composition of ASTM A500 Gr. B.

The new and exquisitely beautiful theatre of Drury-lane has the peculiar contrivance of an iron-curtain to secure the audience from all danger, in case of fire on the stage. Miss Farren, in the occasional epilogue, delivered on opening this new theatre, pleasantly informs the spectators that, should flames burst out in the part appropriated to the representation, they may comfort themselves with thinking that nothing can be burnt but the scenery and the actors.

Middle English iron, iren, yron, from Old English iren, variant (with rhotacism of -s-) of isen, later form of isern, isærn "the metal iron; an iron weapon or instrument," from Proto-Germanic *isarn (source also of Old Saxon isarn, Old Frisian isern, Old Norse isarn, Middle Dutch iser, Old High German isarn, German Eisen). This perhaps is an early borrowing of Celtic *isarnon (compare Old Irish iarn, Welsh haiarn), which Watkins suggests is from PIE *is-(e)ro- "powerful, holy," from PIE *eis "strong" (source also of Sanskrit isirah "vigorous, strong," Greek ieros "strong"), on the notion of "holy metal" or "strong metal" (in contrast to softer bronze). It was both an adjective and a noun in Old English, but in form it is an adjective. The alternative isen survived into early Middle English as izen. In southern England the Middle English word tended to be ire, yre, with loss of -n, perhaps regarded as an inflection; in the north and Scotland, however, the word tended to be contracted to irn, yrn, still detecta

The primary phase of low-carbon or mild steel and most cast irons at room temperature is ferromagnetic α-Fe. It has a hardness of approximately 80 Brinell. The maximum solubility is about 0.02 wt% at 727 °C (1,341 °F) and 0.001% carbon at 0 °C (32 °F). When it dissolves in iron, carbon atoms occupy interstitial "holes". Being about twice the diameter of the tetrahedral hole, the carbon ...

Iron-Cementite diagram is not a true equilibrium diagram, since equilibrium means no change of phase with time, however long it may be. Graphite is more stable form of carbon. Cementite is a metastable phase, which decomposes to graphite if given long periods of time. Graphitisation, however, rarely occurs in steels and may take years to form.

This led to talks of the conductivity of various types of iron, and long story short, I'd like to find a graph of conductivity or resistivity with relation to carbon content. Anybody know where I can find one?

**Electron Structure:** The Group 5 elements are nearing the middle of the transition elements. Group 5 elements have five bonding electrons each due to hybridization (see below), and they are higher melting than the Group 4 elements (Ti, Zr and Hf). This logically follows the idea that the more bonding electrons an element has, the stronger its bonding will be, and therefore the higher the melting temperature. V, Nb and Ta have electron structures of: *(inert gas core) + d^3 + s^2* which hybr...

Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron, often along with substantial quantities of iron, steel, limestone, carbon (coke), and taking various steps to remove undesirable contaminants.
