Hello,

Those refer to commonly seen cracking problems in metal. There are a myriad of origination causes and finding a particular one requires a good metallurgist a lot of work and testing. The same metallurgist will also tell you that some of these, HIC for instance, can be lessened but not avoided. Such a metallurgist might be the professor who assigned you this homework. Have you asked him?

See the following PDF files for stress cracking in metals (HIC, SSC, SOHIC, SZC and HSC): H2S_Cracking - 1 & H2S_Cracking_-_2.

Thank you for the links,

unlikely that I ever will have a need to use metals in these environments, but very good to know, triggred some cautiousness in my thinking.
