CONSMAT QUIZ 4 identification

Ductility

It is the ability of a material to undergo large deformation without fracture

Yield Point

It is the first load at which these is marked increase in strain without an increase in stress

Proportional Limit

It is the greatest stress that a material is capable of without deviating from Hooke's Law

Modulus of Toughness

It is the ability of the material to absorb large amount of energy. It can be related to the area under the entire stress. - Strain Curve

Modulus of Resilience

the resilience of the material is that property of an elastic body by which energy can be stored up in the body by loads applied to it and given up in recovering its original shape when the loads are removed

Modulus of Resilience

A property of an elastic body by which energy can be stored up in the body by loads applied to it and given up in recovering its original shape when the loads are removed

Pig Iron

It is obtained by reducing the iron ore in a blast furnace. This is accompanied by changing alternate layers of iron ore, coke and limestone in continuously operating blast furnace. Blasts of hot air are forced up through the charge to accelerate the combustion of coke while raising the temperature sufficiently to reduce the iron ore to molten iron. the limestone is a flux which unites with impurities in the iron ore to form slag

Wrought Iron

A form of iron that contains slag, is initially malleable but normally possesses little to no carbon and will harden quickly when rapidly cooled

Steel

It is an iron-carbon alloy which is cast from a molten mass whose composition is such that it is malleable in some temperature change

Cementite

It is a hard and very brittle material with a Brinell Hardness of 650 and a diamond hardness of 760

Ferrite

It is a soft, ductile material with Brinell Hardness of 90 and a diamond hardness of 170
