Metals and alloys should have adequate toughness apart fiom other properties like tensile strength, corrosion resistance, creep resistance, fatigue strength etc. This will enable them to withstand impact loading. Toughness depends on temperature, crystal structure etc. An attempt has been made to determine toughness of copper, zinc and tin and their alloys over a range of temperatures fiom 263K to recrystallization temperature (0.4 Tm) Toughness increases as temperature increases, remains constant and then decreases near about the recrystallization temperature for allmetals and alloys tested. The initial increase is due to an increase in dislocation mobility and the final decrease is due to coarsening of grains.
