heat treatment

Question 1

what is heat treatment

Answer 1

is the heating and cooling of metals to change their physical and mechanical properties, without letting it change its shape

Question 2

what is hardening

Answer 2

Only high Carbon Steed can be hardened. heat the Steel with a heat troche or welding torch until it glows red quench in clean water but buttles

Question 3

what is tempering

Answer 3

used to increase the toughness of iron-based alloys. it is usually preformed after hardening done by heating the metal to some temperature below the critical point for a certain point of time, then allowing it to cool in still air

Question 4

what is annealing

Answer 4

is a heat process where by a metal is heated to a specific temperature colour and then allowing it to cool slowly. this softens the metal which means it can be cut and shaped more easily

Question 5

what is normalising

Answer 5

is a similar process to make the metal more ductile
