**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...

Hi everyone, I'm in a Materials and Mechanics class for an engineering curriculum, and my professor was not able to find anything about the differences in the mechanical properties of Hypoeutectoid steels and Hypereutectoid steels for the Iron-Iron Carbide Phase Diagram and why you would choose one over the other specifically for mechanical properties. Just to reiterate, I understand why chemically you would choose one over the other, but not why mechanically, if there even is a reason why. I...

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

This process consists of homogenisation or grain refinement to obtain uniformity in the material microstructure. The material is heated to a temperature above the upper critical line of the iron carbide phase diagram to produce a homogeneous austenitic phase. This is then followed by a cooling phase in slightly agitated air to form ferrite.

TTT diagram of steel indicates the time-temperature and transformation curve. This means transformation is dependent upon time, temperature, and cooling mechanism.

Okay, so after my last post, there was a request for details about phase states other than what we can see documented in the TTT diagram. As I've been writing this, it's kind of evolved into a primer on the different phase states and what they mean. If my last post was too long for you, I'm sorry to say this one is probably longer.

1705, "phase of the moon, particular recurrent appearance presented by the moon (or Mercury or Venus) at a particular time," back-formed as a singular from Modern Latin phases, plural of phasis, from Greek phasis "appearance" (of a star), "phase" (of the moon), from stem of phainein "to show, to make appear" (from PIE root *bha- (1) "to shine"). Latin singular phasis was used in English from 1660 for each of the aspects of the moon. General (non-lunar) sense of "aspect, appearance, stage of development at a particular time" is attested by 1841. Meaning "temporary difficult period" (especially in reference to adolescents) is attested from 1913.
