Caption: Figure 8: Typical Bode: (a) impedance of the interface, [absolute value of Z], and (b) phase angle plots obtained for iron-nickel alloy
: (1) Fe-36% Ni and (2) Fe-45% Ni immersed in 1M HCl solutions.
Using nanoscale imaging, the team looked at the physical structure of tetrataenite, an iron-nickel alloy
, in each meteorite.
"The results confirm that already in the fourth millennium BC metalworkers had mastered the smithing of meteoritic iron, an iron-nickel alloy
much harder and more brittle than the more commonly worked copper.
The team's results show that in the fourth millennium BC metalworkers had already mastered the smithing of meteoritic iron, an iron-nickel alloy
much harder and more brittle than the more commonly worked copper, developing techniques that went on to define the iron age.
An example of such a composite is Invar, an iron-nickel alloy
with a uniquely low coefficient of thermal expansion.
While attempting to develop an inexpensive international standard for the meter, the metric unit of length, Guillaume hit upon an inexpensive iron-nickel alloy
that expands very little when heated.
The new 3.2MW smelter at the Mintek facility is capable of processing around 2,000 tonnes per month and producing Platinum Group Metals (PGMs) in an iron-nickel alloy
at an annualised rate of up to 70,000 ounces per year.
The ferronickel factory, also to be located in Moa, is expected to produce 68,000 tons a year of iron-nickel alloy
This ball is surrounded by a highly dynamic outer core of a liquid iron-nickel alloy
(and some other, lighter elements), a highly viscous mantle and a solid crust that forms the surface where we live.
