The following data were obtained from a series of Charpy impact tests performed on four steels, each having a different manganese content. Plot the data and determine

(a) the transition temperature of each (defined by the mean of the absorbed energies in the ductile and brittle regions); and

(b) the transition temperature of each (defined as the temperature that provides 50 J of absorbed energy)

The following deta were obtained from a series of Charpy impact tests performed on
four ductile cast irons, each having a different silicon content.
(a) Plot the impact energy versus temperature for the four alloys on the same graph.
(b) Datermine the ductile to britlle transition temperature of each alloy (defined as the
temperature that provides 10 J of absorbed energyl.
(e) Plot the ductile to brite transition temperature versus silicon content and discuss
the ettect of silicon on the toughness and ductity of the cast iron.
(d) What is the maximum silicon allowed in the cast iron if a part is to be used at
25'e?
