Residual Stress Assessment in Surface-treated Nickel-base Superalloys
Experimental results are presented to illustrate that there exists a unique window of opportunity for eddy current NDE of residual stress in surface-treated nickel-base superalloys. In light of its frequency-dependent penetration depth, the measurement of eddy current conductivity has been suggested as a possible means to allow the nondestructive evaluation of subsurface residual stresses in su...
متن کاملCorrosion in coal gasification environments at 550 C
Coal gasification combined cycle power plants promise lower emissions and higher efficiencies than conventional pulverized coal power plants. Process economics favor compact, high pressure, slagging gasifiers, usually of the entrained type, for most coals. The high raw gas temperature in such plants prevent the use of uncooled metals in contact with the gas. Direct metal/gas contact usually occ...
متن کاملInternal Friction in Nickel-Base Superalloys in the kHz-Range at Temperatures between 20 °C and 1250 °C
Damping measurements were carried out on two-phase (y-matrix, y'-precipitates) nickel-base alloys containing different volume fractions of y' in order to achieve a better understanding of the strong elastic modus decrease between 1000°C and 1 100°C. For the investigation of the damping a free-free beam flexural vibration technique was applied. Nickel-base alloys with a high volume fraction of y...
متن کاملHigh-frequency eddy current conductivity spectroscopy for residual stress profiling in surface-treated nickel-base superalloys
Recent research results indicated that eddy current conductivity measurements can be exploited for nondestructive evaluation of subsurface residual stresses in surface-treated nickel-base superalloy components. Most of the previous experimental studies were conducted on highly peened (Almen 10-16A) specimens that exhibited harmful cold work in excess of 30% plastic strain. Such high level of co...
متن کاملReview on Thermo-Mechanical Fatigue Behavior of Nickel-Base Superalloys
Nickel-base superalloys have become the key materials of hot-end components in the aeroengines over the past several decades. Nickelbase superalloys are easy to produce thermo-mechanical fatigue (TMF) behavior when withstanding the combined effects of high temperature, creep, oxidation, mechanical stress and thermal stress. The occurrence of TMF seriously affects the normal service for hot-end ...
