Abstract

Advanced high-strength steels (AHSS) have emerged interest in the automotive industry, because of their potential to reduce weight and to
increase fuel efficiency. However, with increasing strength steels become prone to hydrogen embrittlement (HE) and stress corrosion cracking.
Hydrogen absorbed during production or service can easily penetrate the components and lead to time-delayed brittle failure. The delay in time is
crucial, because structural components have to be crack free for the whole lifetime of a car. Successful assessment strategies for AHSS are still
rare and experimental testing is very time consuming and expensive. Furthermore, HE tests performed under controlled laboratory conditions for
limited time and extrapolation to the lifetime of a car needs special consideration.
