WebbCavity walls give better thermal insulation than solid walls. It is because of the space provided between two leaves of cavity walls is full of air and reduces heat transmission into the building from outside. Economically they are cheaper than solid walls. Moisture content in outer atmosphere is does not allowed to enter because of hollow space between leaves. WebbAbstract: Thermal etching is a method which is able to reveal and characterize grain boundaries, twins or dislocation structures and determine parameters such as grain boundary energies, surface diffusivities or study phase transformations in steels, intermetallics or ceramic materials.
