“…(2022) to correlate the SPCT responses for P91 steel and Eurofer97 alloy at high temperature. In Ganesh's work (Ganesh and Laha, 2015), using Chakrabarty's membrane stretch model, the creep strain–time curves of 316 steel at high temperature measured in SPCT tests agree well with the corresponding values obtained from conventional uniaxial creep tests, as shown in Figure 7. Chakrabarty's model is well accepted for the material with an exponential hardening behavior.…”

PurposeThis paper presents a review concerning the analytical and inverse methods of small punch creep test (SPCT) in order to evaluate the mechanical property of component material at elevated temperature.Design/methodology/approachIn this work, the effects of temperature, specimen size and shape on material properties are mainly discussed using the finite element (FE) method. The analytical approaches including membrane stretching, empirical or semi-empirical solutions that are currently used for data interpretation have been presented.FindingsThe state-of-the-art research progress on the inverse method, such as non-linear optimization program and neutral network, is critically reviewed. The capabilities of the inverse technique, the uniqueness of the solution and future development are discussed.Originality/valueThe state-of-the-art research progress on the inverse method such as non-linear optimization program and neutral network is critically reviewed. The capabilities of the inverse technique, the uniqueness of the solution and future development are discussed.

“…Fracture morphology is mainly ductile transgranular, as shown in Figure 11 and Figure 12 . There is the presence of dimples and quasi-cleavage fracture that can also be found in other austenitic steels (e.g., 316L) [ 15 ]. However, the presence of dimples is significantly decreased in creep fracture ( Figure 11 b and Figure 12 c) in comparison with tensile test fracture at high temperature ( Figure 5 b).…”

“…The authors believe that the results presented herein are promising. Based on these results, research should further proceed to broader studies that concentrate on: (i) optimization of specimen dimensions; (ii) testing various materials, such as ferritic-martensitic steels, austenitic steels, light alloys, and others in a similar way as SPT and SPC [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]; and (iii) application to practical tasks for the industry (e.g., determination of weld properties or service life extension in a similar manner as presented in [ 27 , 30 , 31 ]). It is necessary to define the size effect related to the particular microstructures and specimen geometry.…”

“…It can be used for testing irradiated materials to minimize the radiation dose, determining the local properties of weld zones or the remaining life of service exposed parts, the development of new materials available in limited amounts, etc. Different specimen geometries have been introduced in the past for tensile, fracture, and creep properties determination [ 1 , 2 , 3 , 4 , 5 , 6 ], including the well-known small punch test (SPT) and small punch creep test (SPC) [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. The typical shape of the small punch specimen is most often a disc of 8 mm diameter or a square 10 × 10 mm and 0.5 mm thickness.…”

Tensile and Creep Testing of Sanicro 25 Using Miniature Specimens

et al. 2018

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 found to be systematically shorter and creep ductility lower in the miniature test, the minimum creep rates were comparable. The analysis of the fracture surfaces revealed similar ductile fracture morphology for both specimen geometries. One exception was found in a small area near the miniature specimen edge that was cut by electro discharge machining, where an influence of the steel fracture behavior at elevated temperature was identified.

A thorough characterisation of the creep properties of any modern alloy designed for a structural application can be an expensive and timely process. As such, significant effort is now being placed in identifying suitable alternative characterisation techniques. The small punch creep (SPC) test is now widely regarded as an effective tool for ranking and establishing the creep properties of a number of critical structural materials from numerous industrial sectors. Over recent years, the SPC test has become an attractive miniaturised mechanical test method ideally suited for situations where only a limited quantity of material is available for qualification testing. Typically, the method requires only a modest amount of material and can provide key mechanical property information for highly localised regions of critical components. As such, SP creep testing offers a feasible option of determining the creep properties of novel alloy variants still at the experimental stage and the residual life of service-exposed material.
