In fact, according to Guoyin Shen of the Carnegie Institution of Washington, most Earth scientists are persuaded that the iron in the inner core does in fact have a hexagonal-shaped lattice. “Within ...

Think Earth is just a static rock? Dive deep, and you'll find a dynamic world where metals leak, water seeps, and its insides ...

Crystal structure of iron in Earth's inner core. Experiments by Tateno et al. revealed that iron adopts hexagonal-closed-packed structure at ultrahigh-press and temperature conditions ...

Crystal Structures Key to Steel’s Design Flexibility Feb. 7, 2023 Material engineers have mapped out the reasons some steels are better than others and how to make those better still.

Neutron computer tomography at ANSTO has been used in one of the first studies to reconstruct the interior structure of rare iron meteorites non-invasively.

Iron meteorites are mainly made of an iron-nickel alloy with a distinctive crystalline structure known as a Widmanstätten texture. Bands are formed by varying levels of nickel. There can be wide ...

An iron alloy that includes 8 percent silicon, when laser-heated under high pressure, separates into dark silicon-rich regions and bright silicon-poor zones that have different crystal structures ...

Crystal Structures Ferrite. Ferrite (α), is the crystal arrangement for pure iron. This form exists as part of the structure in most steels and can usefully absorb carbides of iron and other metals by ...

The Structure of Metal Metal Basics The Crystals that Make the Metal Let's take a look at a paper clip. A typical paper clip is made up of 1,000,000,000,000,000,000,000 atoms of iron.

AT the recent meeting of the Iron and Steel Institute Messrs. A. Westgren and G. Phragmen presented a continuation of work published by them two years ago at the same Institute. The present paper ...

Directly below the outermost atomic layer, the crystal structure is rearranged and some iron atoms are absent. It is precisely above such places of missing iron atoms that other metal atoms attach.
