The reason that ay annealing process carl softern a cold-worked fe-c alloy is: a) the annealing pröcess decreases the carbon content in the alloy b) the annealing process increases the dislocation density of the alloy c)the annealing process decreases the dislocation density of the alloy d) the annealing process generates the barriers in the micróstructure of the alloy to prevent dislocation motion.
