Download An Electrochemical Model for Hot-salt Stress-corrosion of Titanium Alloys Book in PDF, ePub and Kindle
An electrochemical model of hot-salt stress-corrosion cracking of titanium alloys is proposed based on an oxygen-concentration cell. Hydrogen embrittlement is proposed as the direct cause of cracking, the hydrogen being generated as the results of the hydrolysis of complex halides formed at the shielded anode of the electrochemical cell. The model found to be consistent with the diverse observations made both in this study and by many investigators in this field.

Download Relative Susceptibility of Titanium Alloys to Hot-salt Stress-corrosion Book in PDF, ePub and Kindle
Susceptibility of titanium alloys to hot-salt stress-corrosion cracking increased as follows: Ti-2Al-11Sn-5Zr-0.2Si(679), Ti-6Al-2Sn-4Zr-2Mo(6242), Ti-6Al-4V(64), Ti-6Al-4V-3Co(643), Ti-8Al-1Mo-1V(811), and Ti-13V-11Cr-3A1(13-11-3). The Ti-5Al-6Sn-2Zr-1Mo-0.25Si(5621S) alloy was both the least and most susceptible depending on heat treatment. Such rankings can be drastically altered by heat-to-heat and processing variations. Residual compressive stresses and cyclic exposures also reduce susceptibility to stress-corrosion. Simulated turbine-engine compressor environmental variables such as air velocity, pressure, dewpoint, salt concentration, and salt deposition temperature have only minor effects. Detection of substantial concentrations of hydrogen in all corroded alloys confirmed the existence of a hydrogen embrittlement mechanism.--P. [i].

Download Hot-Salt Stress-Corrosion of Titanium Alloys: Generation of Hydrogen and Its Embrittling Effect Book in PDF, ePub and Kindle
Alloy specimens of Ti-8A1-lMo-lV were salt-coated and exposed to conditions conducive to hot-salt stress-corrosion. Subsequent tensile tests revealed that ductility was strain-rate and temperature sensitive. Embrittlement was more pronounced at slow crosshead speeds in the vicinity of ambient temperature. After salt-exposure ductility was restored by vacuum annealing. Substantial increases in hydrogen content were measured in embrittled specimens. These results demonstrate that hydrogen can be generated during elevated temperature exposure to salt and that the subsequent embrittlement is a manifestation of the phenomenon of "slow-strain-rate" hydrogen embrittlement.
