strength over 1800 MPa are baked for 24 hours at a temperature in the range 190-230°C (4). The aim of the work described in this paper was to investigate the extent to which electroplating with zinc-cobalt alloys causes hydrogen embrittlement of high strength steel. Hydrogen Embrittlement - Heat Treat Doctorre-diffuse out of the steel, and ductility is restored. Performing an embrittlement relief, or hydrogen bake out cycle (the term bake-out involves both diffusion within the metal and outgassing) is a powerful method in eliminating hydrogen before damage can occur. Some of the key variables include temperature, time

Hydrogen Embrittlement in Plating

A. Hydrogen embrittlement is a phenomenon that affects high-strength steel. Hydrogen--often from pickling or plating--invades the grain structure of a high strength steel, making it brittle and subject to catastrophic failure. The best approach is to avoid or minimize processes that cause hydrogen embrittlement.

Temper Embrittlement ::Total Materia Article

The rate and degree of development of temper embrittlement depend on the temperature and time of holding steel within the dangerous temperature interval (450-600°C). With a certain temperature of tempering within this interval, the initial stages of embrittlement appear appreciably sooner than at a higher or a lower temperature. Temper Embrittlement of Pressure Vessel SteelsLukens Steel Company, Coatesvi/le, Pa. ABSTRACT. Temper embrittlement is a particularly important consideration for steels used in high pressure con­ tainment vessels operating in the temperature range of 600 to 1100 F. On this basis, a comprehensive evaluation of commonly used pres­ sure vessel steels and weld metals was undertaken.

Strain ageing occurs when steel containing free (uncombined) nitrogen is strained and heated, either simultaneously or at a later time, to a temperature in the region of 200 °C. Embrittlement results from the incipient precipitation of nitrides. During the 1930s a number of welded steel bridges were erected in Belgium and Germany.
