Hey guys....
Ductile materials do undergo brittle fracture if an impurity of low melting point such as zinc, cadmium is added to high melting point materials such as iron and occupy the sites at grain boundary. Then during heating low melting point metal will melt first and grain boundaries slides on one another and fails in the brittle manner.
The other reason is at low temperatures metal fails in brittle manner.
