Stress Corrosion Cracking of Copper Metals

Liquid metal embrittlement is similar to stress corrosion cracking but is thought not to be identical.The similarities and differences are discussed.Mercury (Hg) is used to test for the presence of residual stress in brass,however Hg is an extremely dangerous metal in contact with any Cu alloy.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456Next475 C (885 F) EMBRITTLEMENT IN STAINLESS STEELSThe nature of this socalled 475 deg C (885 deg F) embrittlement was investigated on a steel containing 27.80% Cr and 9.70% Ni by means of microhardness measuremerts and metallographic studies.It was found that there is a basic difference between the 475 deg C embrittlement and cold short brittleness the latter occurs at higher temperatares.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextTemper-Embrittlement - an overview ScienceDirect TopicsEmbrittlement results from the incipient precipitation of nitrides.During the 1930s a number of welded steel bridges were erected in Belgium and Germany.These were fabricated from Bessemer converter steel which,because of the nature of the process,may contain free nitrogen.

Atomistic calculations using pair potential interactions verified these findings.It was initially thought that the helium embrittlement in metals was due to the trapping and subsequent bubble formation at radiation-induced defects.It has been shown,however,that helium may be trapped in metals even in the absence of radiation damage.Recent Advances in Understanding Helium Embrittlement in Atomistic calculations using pair potential interactions verified these findings.It was initially thought that the helium embrittlement in metals was due to the trapping and subsequent bubble formation at radiation-induced defects.It has been shown,however,that helium may be trapped in metals even in the absence of radiation damage.
