When the temperature of a solid metal increases, its intramolecular bonds are brake and strength of solid metal decreases. Due to decrease its strength, the elongation of the metal increases, when we apply the load i.e. ductility increases.

Introduction:
When the temperature of a solid metal increases, its mechanical properties can be affected. Two important mechanical properties of metals are strength and ductility. Strength refers to the ability of a material to withstand an applied load without deformation or failure, while ductility refers to the ability of a material to undergo plastic deformation before fracturing.
Explanation:
When the temperature of a solid metal increases, the behavior of its atoms and crystal structure changes. This can lead to changes in the mechanical properties of the metal.
Effect on Strength:
When a metal is heated, the thermal energy causes the atoms to vibrate more vigorously, which disrupts the crystal lattice structure. This results in a decrease in the strength of the metal. The increased atomic vibrations make it easier for dislocations to move through the crystal lattice, which leads to plastic deformation and reduces the strength of the metal. Therefore, as the temperature of a metal increases, its strength decreases.
Effect on Ductility:
On the other hand, the increased atomic vibrations also make it easier for dislocations to move through the crystal lattice, which enhances the ductility of the metal. At higher temperatures, the increased mobility of dislocations allows for greater plastic deformation before fracture occurs. This means that the metal becomes more ductile as its temperature increases.
Conclusion:
In conclusion, when the temperature of a solid metal increases, its strength decreases but ductility increases. This is due to the increased atomic vibrations at higher temperatures, which facilitate dislocation movement and plastic deformation. It is important to consider these temperature-dependent changes in mechanical properties when designing and using metal components in various applications.
