The Present Status of the Disk Pressure Test for Hydrogen Embrittlement


This paper is an update of an enormous amount of work done since STP 543. Accept/reject criteria are illustrated as well as numerous parameters examined such as: (1) strain rate, (2) interfacial and geometrical factors, (3) metallurgical factors, and prior embrittlement from other sources or combined mechanisms, for example, gaseous hydrogen embrittlement on previously embrittled titanium or steel.

Applications to sustained load, rising load, cyclic loads and small alternating loads on sustained loads are illustrated.

A large amount of new test results on a variety of material is presented, including welded Inconel 718.
