Because of the total mutual solubility , Ni -Fe alloys are more ductile than about any other ferrous combination. Like any metal , if heavily cold worked ,ductility is reduced. If carbon is added, ductility can be drastically reduced . Generally Ni-Fe alloys are used for unique magnetic properties. Not much else can be said without more information.

Looking up superconducting cables on the net , I doubt very much that any casting is involved ( to produce the final cables). The figures show multiple concentric tubes , some tubes to carry the cooling fluid and other tubes are the conductors and copper and insulation... If it was necessary to combine the copper and conductor into a single tube ( in the ...

There are sliding shafts used for agricultural machinery commonly called a "lemon shaft" and they are available in several sizes.

Silicone grease and paste are frequently meant the same thing. They are used for lubrication and because they wrap the area of application they protect the parts from rust and elements. When they are used in applications such as plumbing orings they have to be rated food grade, or for electrical uses they have to be rated.
Silicone spray is mostly used as ...

According to a couple of textbooks on machine design and assuming that your FBD is correct, the maximum bending moment occurs at the centre of the shaft.
For a point load, it is equal to:
$WL/4 = M$
Where W is the point load and L is the length of your beam.
$(200*10^3)*1/4 = 50*10^3 Nm = 50*10^6 Nmm = M$
According to the maximum shear stress theory ...

Hot work involves macroscopic deformation of the metal; no time is allowed for creep to take place so the concept of "creep" as such doesn't exist during hot work.
The objective of hot work is to deform the workpiece to its desired shape at a temperature at which it happens to be easily malleable and will not strain-harden in the process. This means that ...

It is usually not accurate or precise enough ; primarily because of movement between the jaws or what ever device hold the specimens and the specimen. On metal samples , even an extensometer can make a little irregularity in the beginning of the strain curve as it "seats-in".
