This paper presents a method of evaluating the embrittling effect of hydrogen on metals by measuring the pressure required to burst a small metal disk. The metal disks are clamped, and the system is pressurized until failure occurs. Embrittlement is expressed by the inverse ratio of the rupture pressures of a hydrogen charged disk and the rupture pressure of an uncharged disk of the same material and processing procedures. The disk pressure test (DPT) provides evidence of other causes of… CONTINUE READING
