Answer 8

Alloys with 68% nickel and 29% copper, with small amounts of iron, manganese and other elements

Question 9

Quenching

Answer 9

The process of rapidly cooling a hot metal to lock the atoms in place, creating a very hard but brittle microstructure

Question 10

Hardening

Answer 10

When a drop in temperature make a liquid become a solid in metals with high amounts of carbon

Question 11

Case Hardening

Answer 11

Producing a hard, wear-resistant surface over a strong, tough but malleable core

Question 12

Alclad Aluminum

Answer 12

A corrosion-resistant aluminium sheet formed from high-purity aluminium surface layers

Question 13

Annealing

Answer 13

The process of reheating a material and allowing it to cool slowly in order to remove internal stresses and create a more malleable material

Question 14

Extrusion process

Answer 14

The forcing of metal through an opening in a die, thus causing the metal to take the shape of the die opening

Question 14

Forging

Answer 14

The process of forming a product by hammering or pressing

Question 15

Female Packing

Question 16

Casting

Answer 16

A process in which hot liquid metal is poured into a mold that contains a cutout of the desired finished shape

Question 17

Cold Working/Hardening

Answer 17

Mechanical working performed at temperatures below the critical range resulting in a strain hardening of the metal
