embrittlement

Acoustic-emission techniques have been used to determine the rate of cracking of highstrength steel due to hydrogen embrittlement.

However, he also said the UV will also make fabric fading, embrittlement, strength reduction.

On ageing mechanism of these components, the critical problems are neutron irradiation embrittlement, corrosion damage, fatigue and erosion.

The material embrittlement and residual stress leads to the final brittle fracture of the ball roller.

The main property changes occurring during dehydrochlorination are: hydrogen chloride evolution, coloration, and embrittlement.

By analytical testing the material discovered that it has high temperature temper embrittlement.

It is found that intermediate temperature embrittlement and temper embrittlement are induced by the critical time of NGS for solute.

Hydrogen embrittlement is an outstanding problem when high strength aluminium alloys are applied in the corrosive environment.

Rework that requires low-hydrogen embrittlement (LHE) cadmium stylus plating should be performed when the component is not loaded.

boiling, the towel should be fully immersed in water, avoiding contact with air oxidation and the increase in strength even embrittlement.

Results show that the alloy in aging state, especially in deformation-aging state, is apparently susceptible to hydrogen embrittlement.

When steels employed, the critical time should be avoid to prevent appearance of temper embrittlement.

Its subject coverage includes: role of hydrogen, factors affecting embrittlement after heat treatment, and preventive measures.

The embrittlement of the wall materials of the reactor was caused by the retained hydrogen and the reactor was damaged.

This failure, which may occur in a short period of time and often is evidenced by cracks in the steel, is called hydrogen embrittlement.

Figure 17 is a scanning electron microscope view of a typical hydrogen embrittlement crack where separation occurs along grain boundaries.

The results of the experiment show that it is effective to prevent hydrogen embrittlement failure by hardening and tempering treatment.

The results show that the one-step temper embrittlement (OSTE) is the main factor to cause the crack of engine exhaust pipe washers.

The reason for hydrogen embrittlement fracture is incomplete removal of hydrogen after acid-washing or electroplating.

Soldering on ADI surface decreased the ADI tensile strength and elongation, and solder coating could not prevent from water embrittlement.

After irradiation, the steel will have different tendency of embrittlement .

Hydrogen embrittlement is not a major influence on fatigue life.

Hydrogen embrittlement can become important in martensitic steels.

The remainder of arsenic and tin in large amount have increased the sensitivity to the. embrittlement.

The mechanism and phenomenon of embrittlement and method of diagnoses has been systematically investigated.

Eventually hydrogen becomes fixed in traps in the metal, leading to hydrogen embrittlement .

Solid-metal embrittlement by cadmium can occur at temperatures below the cadmium melting point.

And thereby settlement for embrittlement was suggested as follows: activation with acidic salt instead of pickling for degreased products.

aerospace series . hydrogen embrittlement of steels . test by slow bending.

The microstructural anomalies resulting from cadmium embrittlement can lead to component fractures in service.

Research methods on hydrogen embrittlement are reviewed .

The embrittlement of the welds increases with the increase of quenching temperature of PWHT.

In ths course of rust-removing, there is no acid mist and hydrogen embrittlement.

However, embrittlement occurs in some metals at elevated temperatures and pressures.

The effect of inhibitor on hydrogen embrittlement of high strength steel has been studied by potentiodynamic polarization technique.

It is the character for fracture of hydrogen embrittlement of high yield steel.

The result show that the materials embrittlement was because of overhigh hydrogen content which displayed crack delay.

In addition, based on the critical time characteristic, the NGS mechanism on temper embrittlement will be summarized.

The cardinal cause of Hydrogen Embrittlement in metals is that hydrogen affects motion, distribution and structure of dislocation.

Embrittlement in metals is that hydrogen affects motion, distribution and structure of dislocation.

Figure 16 shows a flap track that cracked because of hydrogen embrittlement 149 flight cycles after overhaul.
