Effect of Hot Isostatic Pressing on Fatigue Life of Cast Aluminium Alloy-354

Abstract:

Cast aluminium alloy 354 finds extensive applications in the automobile and aerospace industry due to its attractive combination of mechanical properties and excellent castability. A high fatigue strength value is desirable for these applications. The present study explores the possibility of improving the fatigue life of cast aluminium alloy by subjecting it to Hot Isostatic Pressing (commonly known as Hipping). A three parameter Weibull analysis of the fatigue test results was carried out for both Hipped and Non-Hipped samples. The Hipped samples showed an improved fatigue life compared to the Non-Hipped samples.
