Answer: Option C. -> Magnalium
The aluminium alloy made by melting aluminium with 2 to 10% magnesium and 1.75% copper is called magnalium

Answer: Option A. -> Ferritic stainless steel
A steel containing 16 to 18% chromium and about 0.12% carbon is called Ferritic stainless steel

Answer: Option A. -> 87.75% Sn, 4% Cu, 8% Sb, 0.25% Bi
White metal alloys are those which are light-coloured and generally have a lead or tin base. These alloys are known as Babbitt metal
Babbitt metal contains 87.75% Sn, 4% Cu, 8% Sb, 0.25% Bi

Answer: Option D. -> Silicon
Silicon increases strength and hardness but to a lesser extent than manganese. It is one of the principal deoxidizers used in the making of steels to improve soundness, silicon is detrimental to surface quality, especially in the low carbon, resulphurized grades. It aggravates cracking tendencies when the carbon content is fairly high.

Answer: Option C. -> Which are deoxidized in the ladle with silicon and aluminium
Killed steels are those steels Which are deoxidized in the ladle with silicon and aluminium

Answer: Option D. -> Boeschinger effect
The Bauschinger effect refers to a property of materials where the material's stress/strain characteristics change as a result of the microscopic stress distribution of the material.
For example, an increase in tensile yield strength occurs at the expense of compressive yield strength

Answer: Option B. -> A mixture of tar and burnt dolomite bricks
The Bessemer process is an industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.
The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron.
In basic Bessemer process, the furnace is lined with a mixture of tar and burnt dolomite bricks.

Answer: Option D. -> Chromium
Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium.
Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'.
This prevents any further corrosion of the surface.
Increasing the amount of Chromium gives an increased resistance to corrosion.

Answer: Option C. -> γ-iron
Gamma iron is an allotropic form of iron existing between the temperature 910°C and 1400°C and having a face-centered cubic lattice.
It is a metallic, non-magnetic allotrope of iron or a solid solution of iron with an alloying element.

Answer: Option C. -> Tin base alloy
Babbitt metal is a soft alloy of tin.
Babbitt metal contains 89.3% tin, 7.1% antimony and 3.6% copper.
