van Leeuwen, H.P. (author), de Rijk, P. (author), Boogers, J.A.M. (author), Huisman, H.N. (author), Wanhill, R.J.H. (author)Circumferentially notched round specimens of 4340 type steel have been plated in a galvanic bath known to be embrittling. The specimens were reclaimed by stripping and baking. Half the specimens were replated in a non-embrittling bath. Reclamation did not remove all traces of hydrogen embrittlement, but raised the threshold stress to such a...report 1979

van Leeuwen, H.P. (author), Schra, L. (author)The literature is reviewed with respect to: - tests conducted to investigate crack re-initiation under dynamic load and arrest of a running crack - metallurgical sources of rate effects - available data for aerospace engineering materials - mechanical sources of rate effects, i.e. dynamic crack tip stresses and kinetic energy effects Conclusions...report 1975
