TC10 Scope

Following a Kick-Off Workshop at GKSS in 1990 related to the topic of "Environmentally Assisted Cracking", EAC, the group was formally established as ESIS TC 10 in 1991.

In 1995, a Subcommittee on “Hydrogen Degradation” was founded following an initiative of members of the Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine.

In the past, the work of TC 10 was focused on the development of innovative methods for testing of EAC and on the elaboration of fracture control guidelines for controlling EAC; as a result, a new ISO standard on accelerated EAC testing was introduced.

Now, TC 10 takes up new EAC and HD related tasks for which the open and versatile structure of the group appears ideally suited. Knowledge Management in the area of environmental/hydrogen degradation/embrittlement/corrosion of metallic materials and the solution of complex technical problems are new challenges. Recent advances in damage mechanisms and their prevention; materials properties under environmental/hydrogen degradation; inspection and control; risk assessment; corrosion management are considered.

The main topics covered by ESIS TC10 are:

  • Environmentally assisted crack growth
  • Environmentally assisted degradation of materials
  • Stress corrosion cracking
  • Corrosion and hydrogen fatigue
  • Hydrogen induced cracking and blistering
  • Hydrogen assisted cracking
  • Mechanisms of embrittlement
  • Corrosion-erosion
  • Fretting corrosion
  • Effects of thermal, mechanical and surface treatments on environmentally assisted cracking
  • High temperature hydrogen attack
  • Advanced methods for characterizing hydrogen - metal interactions
  • Hydrogen - metal interactions: electrochemically generated hydrogen, hydrogen generation in gaseous environments
  • Engineering perspectives and approaches to hydrogen challenges
  • Evaluating material performance for hydrogen service
  • Hydrogen dissolution, transport, and trapping
  • Mechanisms of intergranular cracking
  • Hydrogen-deformation interactions
  • Liquid metal embrittlement
  • Irradiation assisted fracture
  • Computational approaches to the process of embrittlement or degradation
  • Modeling and simulation
  • Case studies
