Iron(Fe),platinum(Pt),molybdenum(Mo),nickel(Ni),palladium(Pd),zinc(Zn), andcopper(Cu) are transition metals. Thepost-transition metalsare those metals that come after the transition metals, but before the noble gases within a row. There are only eight of them, but they can take on some...

In conclusion, we have performed computational simulations on the possible incorporation of a range of elements into the Earth’s core, by considering the thermodynamic stabilities of corresponding Fe alloys. At high pressure, many elements, that are typically assumed lithophile or chalcophile, may co...
Chemical elements are entities which are defined by having a set number of protons in their nucleus. Chemical elements which give up electrons in chemical reactions are known as metals while those that tend to gain electrons are known as non metals....
A series of β-γ Ti-44Al-8Nb-0.2B-0.2Y alloys have been modified with 0.5 to 2.0 at.% of the β-stabilizing elements Mn, Cr, Mo and V. Additions of Cr and Mo alone result in a decrease in the flow stress, whereas the opposite effect was observed for
