A system comprises a casing and a liner. The liner is concentric with the casing and the casing is disposed in a borehole. A layer of material disposed between the liner and the casing. The layer of material forms a first bond with the liner and a second bond with a metal alloy disposed on an inner surface of the casing thereby enabling hanging the liner from the casing. The layer of material is an expandable metal disposed upon a tapered surface of the liner. The layer of material contacts the metal alloy along a circumferential surface of the layer of material. The layer of material comprises a product of an exothermic reaction package; where a product is produced by an exothermic reaction of a metal with a metal alloy.
