R. Kocik et al., INVESTIGATIONS OF INITIATION OF INTERCRYS TALLINE FATIGUE CRACKS OF INTERSTITIAL-FREE (IF-) STEELS, Materialwissenschaft und Werkstofftechnik, 28(6), 1997, pp. 287-292
While investigation the fatigue strength of interstitial free steels,
intercrystalline fatigue cracks have occurred as a damage which could
reduce the application range of this material, being well-known for it
s excellent depth drawing features. Through metallographic examination
the known causes of the damage like formation of grain cover tertiary
zementit of precipitations on the grain boundaries could be excluded.
In this paper investigation results are represented which are receive
d through high-resolution analyses techniques (TEM, AES).
