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.

The propagation of fatigue cracks in various aircraft parts has been the subject of extensive study. The accompanying data consists of propagation lives (flight hours/10 $^{4} )$ to reach a given crack size in fastener holes for use in military aircraft $($ "Statistical Crack Propagation in Fastener Holes Under Spectrum Loading," J. Aircraft, $1983 : 1028-1032 ) :$
