Explain why fatigue and SCC failures are much more dangerous than ductile rupture.
What is stress corrosion cracking (SCC)? Which element in the body is the key factor that causes SCC of 316L stainless steel implants?
SCC typically occurs in stainless steels that work in a chloride-rich medium. In these situations, Cl- or OH- ions are key environmental species that cause SCC in stainless steels.
Would SCC occur in a hip replacement implant that is made of a martensitic or ferritic stainless steel? Explain your answer.
