Hydrogen diffusivity in MS1700 and QP1180 AHSS

Devanathan-Stachurski permeation tests were carried out on a grade 1700 Martensitic Advanced High Strength Steel (MS-AHSS) and Quenched and Partitioned (QP) AHSS grade 1180 to obtain the effective diffusivity coefficient. Data reported in terms of normalized time (s/m^2) VS normalized flux.
