Engineering Materials
When a steel containing __________ 0.8% carbon is cooled slowly below the lower critical point, it consists of ferrite and pearlite.
Is produced by small additions of magnesium (or creium) in the ladle. Graphite is in nodular or spheroidal form and is well dispersed throughout the material
Contains 1.7 to 3.5% carbon in Free State and is obtained by the slow cooling of molten cast iron
Is produced by annealing process. It is soft, tough and easily machined metal
Is also known as chilled cast iron and is obtained by cooling rapidly. It is almost unmachinable
