Under predetermined temperature, permanent load is applied to smooth cross-section sample, is generated at any time using extensometer measurement sample marking distance section
Deformation, when record m- deformation data.For the ease of extensometer clamping, tested sample both ends need to process lug, and retain a fixed length
The clamping space of degree, sample should have longer gauge length section (generally at least 16mm) to adapt to extensometer minimum range, gauge length
Section diameter is generally at least 5mm, to prevent lug and gauge length section diameter great disparity, leads to lug strength reduction, in this way since, one
The total length of creep sample often about needs 100mm even more.Using a large amount of multiple inside aero-engine and gas turbine
Miscellaneous thin-wall construction (the most thin-walled thickness of such as hollow turbine vane is about the several millimeters of zero point), since there are rulers for material creep performance
Very little effect, the croop property data of traditional standard sample are unable to satisfy the design requirement of complex thin-wall structure, this just needs to carry out
The creep test of components (such as blade) body sampling or design and the comparable thin-walled of components wall thickness (or pole) small sample,
Obtain the croop property data for adapting to components body dimension range.
For a long time, the requirement due to mechanical extensometer to specimen size is high, and non-contact measurement method accuracy is low, high
The reasons such as temperature measurement effect difference increase the measurement difficulty of the small sample deformation of creep, and the small sample creep for lacking mature and reliable is surveyed
