Because when material is heated than the grains inside the material separates and results in lower toughness.

When material is heated then bonding between grains of material become weak so its toughness decrease.

After heating the metal the toughness will be decrease because of molecules will separates.

After heating toughness of material will be decrease of inside grain structure change.

Toughness increases with increase in temperature as well as ductility also increases.

How it can decrease? If a material is heated toughness and ductility both increases.

Toughness will increase after heating because grain get refine and rearrange.

Because after heating metal will be softened so toughness will decreases.

Toughness will increase or decrease, it depends on the type of material.

As material gets loosen in grain growth it decreases it's toughness.
