Evaluation of current methods for creep analysis and impression creep testing of power plant steels
Destructive testing of creep exposed components is a powerful tool for evaluation of remaining lifetime of high temperature pipe systems. The most common destructive evaluation method used today is uniaxial creep testing. Uniaxial creep tests can produce accurate creep curves but the test method has some drawbacks such as costliness and long testing times. It also demands large sample material ...
متن کاملImpression Testing of Self-Healing Polymers
As part of the BIOSANT program (biologically-inspired smart nanotechnology), scientists at NASA-Langley have identified a “self-healing” plastic that spontaneously closes the hole left by the passage of a bullet. To understand and generalize the phenomenon in question, the mechanical properties responsible for this ability are being explored. Low-rate impression testing was chosen to characteri...
متن کاملDevelopment of a new creep testing equipment to obtain long-term deformation parameters of salt rocks
Creep phenomenon in rock engineering plays a key role in development of underground spaces as they must be stable enough for a long period of time. Current research involved designing and manufacturing of a new creep testing machine. The equipment is capable to perform simultaneous light-duty creep tests on more than one cylindrical rock samples at a very low cost.To evaluate the equipment’s pe...
متن کاملConstruction and validation tests of a micro-impression creep test machine
A micro-impression creep machine was designed and developed, adopting a small punch in diameter of 150 um, displacement gage with sub-μm-scale accuracy, and a load-cell with mN-scale accuracy of in an effort to investigate the creep behavior of a small solder ball with a diameter of less than 1 mm. The creep behavior of a lead-free solder ball (Sn-3.0Ag-0.5Cu) with a diameter of 760 μm was inve...
متن کاملTensile and Creep Testing of Sanicro 25 Using Miniature Specimens
Tensile and creep properties of new austenitic steel Sanicro 25 at room temperature and operating temperature 700 °C were investigated by testing on miniature specimens. The results were correlated with testing on conventional specimens. Very good agreement of results was obtained, namely in yield and ultimate strength, as well as short-term creep properties. Although the creep rupture time was...
