Assessment of tensile strength using small punch test for transversely isotropic aluminum 2024 alloy produced by equal channel angular pressing

Critical evaluation of the small punch test as a screening procedure for mechanical properties

“…One circular crack occurs during ductile failure whilst the brittle failure is characterised by several edged cracks. Other authors used the macroscopic appearance of the cracks as an additional screening criterion for ductility of the material [19,20].…”

Anisotropy of uni-axial and bi-axial deformation behavior of pure Titanium after hydrostatic extrusion

“…It is deformed at room temperature by a well lubricated hemi-spherical rigid punch having a diameter of 2.4 mm. The die design is similar to that widely used for small punch testing [28][29][30][31][32][33]. Punch speed during testing was 0.5 mm/ min.…”

Deciphering deviation in mechanical properties of differently processed AISI 316L austenitic stainless steel using the small punch test

“…These MST techniques in general include miniature tensile test [1,2], shear punch testing [3,4], small punch test (SPT) [5][6][7][8][9], and indentation test [10]. They are widely applied in the nuclear and petrochemical industries, such as testing of properties of irradiation material [1,9,11], post-irradiation examination [12][13][14], failure analysis [15], new materials screening [16] and remaining life assessment of inservice components [17]. Also, these techniques are capable of characterizing mechanical properties of those materials which are processed by special deformation means [16,18].…”

Also, these techniques are capable of characterizing mechanical properties of those materials which are processed by special deformation means [16,18]. Generally, there are mainly two reasons that drive the development of these techniques: one arises from limitations of the standard testing, in case when the mechanical testing is difficult to carry out by conventional standard tests and the other advantage is to reduce as much as possible the cost of sampling and testing.…”

“…Amongst the various MST techniques, SPT has received particular attention mostly because it has excellent sensitivity to various characteristics of materials and better agreement with the data obtained by SPT and other conventional mechanical tests, such as conventional tensile test (CTT) [11,16,19], hardness test [20,21], Charpy test [22,23], fracture toughness test [24,25] and creep test [26][27][28]. It has also been known that microstructural characteristics play an important role in controlling mechanical properties, especially in polycrystalline metals and alloys, where microstructure can be generally considered as the combination of morphology of grains and their crystallographic orientation.…”
