Development of Ultrasonic Fatigue for Rapid, High Temperature Fatigue Studies in Turbine Engine Materials
A system for ultrasonic fatigue testing at temperatures as high as 700 C and at positive mean stresses has been developed. Its use is demonstrated by examining the fatigue behavior in the lifetime range of 10 to 10 cycles for the nickel-base superalloy Rene' 88 DT at 20 and 593 C for a load-ratio of 0.05. Crack initiation occurred from large grains and from inclusions, consistent with crack ini...
متن کاملUltrasonic Thermometer for High Temperature Materials Testing
This past year there were a total of 14 faculty members involved in 40 sponsored research projects. Sponsors included government agencies, navy labs and industry. In addition to the sponsored faculty research there were 15 midshipmen involved in independent research projects with faculty, four of which were Bowman Scholars. Many of these projects were also funded by outside sponsors. Overall, 2...
متن کاملHigh temperature ultrasonic transducers: review
The problems of development of high-temperature ultrasonic transducers for modern science and technology applications are analysed. More than 10 piezoelectric materials suitable for operation at high temperatures are overviewed. It is shown that bismuth titanate based piezoelectric elements are most promisable. Bonding methods of piezoelectric elements to a protector and backing are discussed. ...
متن کاملFatigue and ultrasonic testing of epoxy-glass composites
Purpose: The purpose of this paper was to find relationship between the degree of strength degradation caused by fatigue and the changes of ultrasonic wave characteristics such as wave velocity and damping coefficient. Design/methodology/approach: Epoxy-glass composites were subjected to oscillatory bending loadings with constant deflection. During fatigue procedure the force needed to achieve ...
متن کاملRedesigning axial-axial (biaxial) cruciform specimens for very high cycle fatigue ultrasonic testing machines
The necessity to increase performances in terms of lifetime and security in mechanical components or structures is the motivation for intense research in fatigue. Applications range from aeronautics to medical devices. With the development of new materials, there is no longer a fatigue limit in the classical sense, where it was accepted that the fatigue limit is the stress level such that there...
