Abstract
Surface scratch has significant influence on the fatigue behavior of Ti-5Al-2Zr-4Mo-4Cr. In this paper, fatigue test with three different surface roughness are conducted, test results are recorded, including test data and fracture characteristics. The distribution of test data is analyzed and the fracture characteristics are discussed according to the change of surface roughness. Study of fatigue behavior of Ti-5Al-2Zr-4Mo-4Cr with surface roughness is significant intheoretical and engineering fatigue study.
