Determination of creep properties of P91 by small punch testing
Materials at High Temperatures, 2015Small punch creep testing was conducted to determine creep properties of P91 at 873 K. The procedure followed the European Code of Practice for Small Punch Tests. Results of small punch creep test and finite element analysis were compared and discussed.

Development of Compact Small Punch Creep Testing Equipment
Volume 6: Materials and Fabrication, Parts A and B, 2011Japan has many aged thermal power plant facilities and some boilers in such facilities have been in operation for more than 100,000 hours, so the importance of creep residual life evaluation of components exposed to severe conditions has been increasing.

Modelling and Data Interpretation of Small Punch Creep Testing
Volume 6: Materials and Fabrication, Parts A and B, 2011The small punch testing (SPT) technique has been proposed for use in determining the creep properties of materials for which only a very small volume of material is available. A draft code of practice on SPT has been produced. However it is not, as yet, generally accepted that the data obtained from small punch tests can be directly related to those ...

Creep small-punch testing and its numerical simulations
Materials Science and Engineering: A, 2009Comparison of results of creep small-punch tests (SPTs) on miniaturized discs with results of their simulation by means of finite element method (FEM) is presented. Advanced heat-resistant chromium steel of type P91 was selected for the investigations. Two basic creep constitutive models, i.e.

Local Creep Evaluation of P92 Steel Weldment by Small Punch Creep Test
Acta Mechanica Solida Sinica, 2008Abstract The aim of this research is to evaluate the local creep damage of various microstructures such as coarse grained heat affected zone (CGHAZ), fine grained heat affected zone (FGHAZ), intercritical heat affected zone (ICHAZ) known as Type IV region, weld metal, and base metal of P92(9Cr-2W) steel weldment by small punch (SP) creep test at 600 ...

Creep Property Evaluation of Heat-Resistant Steels by Small Punch Creep Test
Materials Science Forum, 2007The recently developed small punch (SP) creep test was applied to four different heatresistant ferritic steels, namely, two kinds of conventional ferritic steels which had been actually used in the high-temperature components for long periods and two advanced high chromium ferritic steels for fusion reactor materials to investigate the applicability of

Appraisement of Creep Properties of 12Cr1MoV Steel by Small Punch Creep Test Method
Materials Science Forum, 2005The numerical simulation for the Small Punch creep (SP-C) tests is conducted using a Finite Element method. The objective of the present study is to obtain the deformation states of the SP-C specimen and to estimate the feasibility of SP-C test method for high-temperature creep properties.

Creep damage in small punch creep specimens of Type 304 stainless steel
International Journal of Pressure Vessels and Piping, 2007Abstract Small punch creep tests on Type 304 stainless steel have been performed at 650 °C. Based on these tests, a finite element model, with modified Kachanov–Rabotnov creep damage constitutive equations, was established. The variation of central deflection and creep strain with time and the evolution of creep damage under constant loads were ...

Response Surface Methodology for the Remaining Creep Life Estimation by the Small Punch Creep Test
Journal of Testing and Evaluation, 2018Abstract In this article, a method for the estimation of the remaining creep life of steel alloy was studied using the response surface methodology (RSM) based on the central composite design (CCD). Small punch creep tests (SPCT) were performed on the specimens from the aged materials of SA-304L alloy, with different consumed creep life ...
