reducing the ore with carbon in the presence of a flux

Question 8:The ability of a material to absorb energy in the plastic range is called

toughness

Question 9:Brass is an alloy of

copper and zinc

yield point increases

ductility decreases

ultimate tensile strength increases

Question 14: Which of the following has a fine gold colour and is used for imitation jewellery?

Aluminium bronze

manganese

Question 16:Dye penetrant method is generally used to locate

surface defects

Question 17: A small percentage of boron is added to steel in order to

increase hardenability

Duplex process

Question 19:The unit cells

contain the smallest number of atoms which when taken together have all the properties of the crystals of the particular metal

have the same orientation and their similar faces are parallel

may be defined as the smallest parallelopiped which could be transposed in three coordinate directions to build up the space lattice
