... intergranular and transgranular cracking. Cox ( Ref 11.49 ) indicates that the mechanism for intergranular cracking is established relatively easily. In most cases, it appears to be a dissolution process, and weight losses are generally observed. One exception is the phenomenon observed in fused salts. Here the...
