Superconductivity and electron concentration

The conditions make it likely that the main effect is the change of electron concentration. In particular, molybdenum, reported to be a nonsuperconductor, is rendered superconducting by small percentages of rhodium. THE purpose of this paper is to show how super conducting transition temperatures of certain systems can be varied by essentially changing the electron concentration, while the average mass

The role of electron concentration in softening

The role of electron concentration in softening and hardening of ternary molybdenum alloys An investigation was conducted to determine softening and hardening behavior in ternary Mo alloys and to correlate these effects with electron concentration. Results showed that the hardness behavior of ternary Mo alloys could be correlated with results anticipated from binary data based upon

Alloy hardening and softening in binary

Alloy hardening and softening in binary molybdenum alloys as related to electron concentration An investigation was conducted to determine the effects of alloy additions of hafnium, tantalum, tungsten, rhenium, osmium, iridium, and platinum on hardness of molybdenum. Special emphasis was placed on alloy softening in these binary molybdenum alloys.

Alloy hardening and softening in binary

At solute concentrations where alloy softening was observed, the temperature sensitivity of hardness was lowered. For solute elements having an excess of s + d electrons or fewer s + d electrons than Mo, alloy softening and alloy hardening can be correlated with the difference in number of s + d electrons of the solute element and Mo.

Molybdenum

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered in the sense of differentiating it as a new entity from the mineral salts of
