Hot tear casting is the discontinuity or failures occurs during cooling or solidification phase in casting process. It is also known as hot crack
In case when the casting is of weak metal, when it is hot and casted, during the process residual stresses cause failures or discontinuity in casting as it cools resulting in hot tears i, e., material casted is partly liquid and partly solid.
