How to use Nickel-steel in a sentence
They also tested several varieties of nickel-steel in the form of both ovoids and wires.
Bidwell's results for iron and nickel were confirmed, and it was further shown that the elongation of nickel-steel was very greatly diminished by tension; when 2 Joule believed that the volume was unchanged.
Thus it has been proved that in annealed cobalt and in nickel-steel there is no Villari reversal.
Guillaume' the temperature at which the magnetic susceptibility of nickel-steel is recovered is lowered by the presence of chromium; a certain alloy containing chromium was not rendered magnetic even by immersion in liquid air.
In a 29% nickel-steel, magnetization increases the constants by a small amount.Advertisement
A nickel steel containing 36% of nickel has the property of retaining an almost constant volume when heated or cooled through a considerable range of temperature; it is therefore useful for the construction of pendulums and for measures of length.
They are non-magnetic or very feebly magnetic. But the critical points of such nickel steel though thus depressed, are not destroyed; and if it is cooled in liquid air below its Ar, it passes to the a state and becomes magnetic.
Manganese steel and nickel steel form an important exception to this rule, in being at once very strong and hard and extremely ductile.
For instance, following Krupp's formula, the side and barbette armour of war-vessels is now generally if not universally made of nickel steel containing about 3.25% of nickel, 0.40% of carbon, and 1.50% of chromium, deeply carburized on its impact face.
Here the merit of nickel steel is not so much that it resists perforation, as that it does not crack even when deeply penetrated by a projectile.Advertisement
Much of the heavy side armour of war-vessels (see Armourplate) is made of nickel steel initially containing so little carbon that it cannot be hardened, i.e.
