1. Introduction 1. Introduction

The role of non-metallic inclusions in steel performance has received considerable attention in the scientific community, in particular to determine the effects of the afore-said inclusions on fatigue behavior of the steel in air (Eid and Thomason, 1979; Fowler, 1979) as well as in hydrogen environment (Chapetti et al., 2003a, 2003b). The role of non-metallic inclusions in steel performance has received considerable attention in the scientific community, in particular to determine the effects of the af re-said inclusio s on fatigu behavior of the steel in air (Eid and Thomason, 1979; Fowler, 1979) as well as in hydrogen environment (Chapetti et al., 2003a, 2003b).
