5.3. Weights of the raw materials using in initial mixtures, weight of alloys and concentrations of the elements in final alloy are given in the table. By using this table, draw the chromium and iron efficiencies (%) graphs depend on the stoichiometric amounts of aluminum powders. Also, draw the graph of amounts of Cr, Fe, Al (g) in the alloy depends on the stoichiometric amounts of aluminum powders.
