文摘
- •
The drop of ductility of the low-carbon steel is caused by action of mobile hydrogen.
- •
The nucleation and growth of the “fisheyes” defects occurs during the necking stage.
- •
No acoustic emission has been detected in relation to the formation of “fisheyes”.
- •
Formation of “fisheyes” cannot be explained by a decohesion mechanism.
