Sentences with word «embrittlement»

A team of researchers found that randomly selected, high - angle, general grain boundaries in a nickel - bismuth (Ni - Bi) polycrystalline alloy can undergo interfacial reconstruction to form ordered superstructures, a discovery that enriches the theories and fundamental understandings of both grain boundary segregation and liquid metal embrittlement in physical metallurgy.

Albany has been used for simulations to determine the effects of hydrogen embrittlement in metal allows.

For example, reactor vessel embrittlement [or loss of ductility] is a major issue.

After radiation exposure, Ju Li says, «we see pores in the control sample, but no pores» in the new material, «and mechanical data shows it has much less embrittlement.»

For example, industry should establish a standard laboratory test method to assess how susceptible bolting materials are to cracking and embrittlement from exposure to hydrogen.

Why it Matters: Combating intergranular embrittlement and disintegration is necessary for preventing metal alloy failure during service life, yet oxidation remains a potentially dangerous obstacle to overcome.

The cracks are due to hygric and thermal stresses, embrittlement due to aging, and building movement.

In that earlier work, researchers discovered this bilayer interfacial phase that is responsible for the mysterious liquid metal embrittlement in nickel - bismuth, but the exact atomic structures of the bilayers had not been determined at that time.

Specific to this nickel - bismuth system, such interfacial superstructures are the root cause of a mysterious phenomenon called «liquid metal embrittlement,» wherein a normally ductile nickel metal or nickel - based alloy can fail catastrophically in an extremely brittle manner in contact with a bismuth - based liquid metal.

While researchers have been studying hydrogen embrittlement for decades, Yildiz says, «almost all of the work has been on what happens to hydrogen inside the metal: What are the consequences, where does it go, how does it lead to embrittlement?

For a given amount of exposure to radiation, the tests have shown the amount of embrittlement is reduced about five to tenfold.

The huge total interfacial area of these 1 - D nanostructures provides a way for radiation - induced point defects to recombine in the metal, alleviating a process that also leads to embrittlement.

We review the most suitable grounds for each type of popular support and painting and review factors influencing the embrittlement of the paint film and what artists can do to prolong its life.

The exposure to ultra-violet light leads to embrittlement and a decrease in elasticity of the system.

The acrylic content also interferes with hydration and makes the lamina more sensitive to carbonation — a reaction with atmospheric carbon dioxide — that leads to embrittlement and a decrease in elasticity.

And if you were one of those guys who took the hard classes and thermo and calc and worried about Neutron embrittlement, you have my genuine respect.
