    What is a discontinuity called, when it is produced during solidification of the molten metal?

    Hot cracking is caused when the contracting and cooling metal is restrained by the mold – or by a thinner section of material that has already cooled and again exposed to heat. Gas holes or porosity are small defects made by gases escaping from the molten metal.

    Was that you are asking or you are also interested in knowing the Inspection Methods that can be used to find out such defects??

    Inherent discontinuities are created when metal is molten and malleable during the casting process. Inherent wrought discontinuities are associated with the melting and the solidification.
