“…In order to develop testing procedure for characterization of small material volumes, microtensile test technique was developed [11][12][13][14]. The experimental specimen dimensions were proposed so, that the test can be run on the same material volume as long time used small punch test.…”

“…Therefore the anisotropy and heterogeneity of mechanical properties are usually determined only from hardness measurement. Recently miniature specimen tensile testing methodology was developed [11][12][13][14]. In comparison to the small punch test for this procedure no correlation has to be known and mechanical properties can be determined directly from the test.…”

The main reason why new technologies and treatment procedure are being developed is to attain special mechanical properties. However, these developments are nowadays done on a small material volume either using some laboratory simulators, applying sever plastic deformation procedures or chemical composition screening for multicomponent alloys development by laser or electron beam melting. In all these application a small volume of the material assessed is available and standard procedures for crucial mechanical properties determinations are not applicable. Thus small size techniques should be applied. There has been extensively used small punch test technique (SPT) for those cases in recent years. This technique is mainly based on the evaluation using correlation between standard and SPT tests for considered material. In cases when insufficient material volume is available, those correlations cannot be established and thus comparative evaluation only can be carried out. This kind of evaluation is insufficient for the contemporary purposes, when full material potential is to be utilized. Therefore, procedures providing results directly comparable with standard specimens are being developed. Fundamental properties are those determined from tensile tests. The current paper is presenting application of developed miniature tensile test specimen method to materials after SPD processes. Quasi static properties determination is shown here for Magnesium and Titanium alloys for ECAP and Rotary Swaging SPD techniques. The results obtained from testing can be used not only for a direct material properties assessment and comparison, but also as input data for FEM codes, significantly increasing the materials considered application potential assessment.

“…Hence, standard tensile specimen shape is possible to use and evaluate according to appropriate standards [6]. However, the efforts to use miniature testing specimens [7] can reduce the need for testing material and lower the final costs of experimental programs. As-sprayed CS coatings are normally characterized by high strength and low ductility [3], which lead to deterioration of fracture properties, though the heat treatment (HT) can improve CS ductility for certain materials [4,5].…”

The article is aimed on material properties evaluation of Ni and NiCr Cold Spray layers by means of proportional small specimens. For the purpose of testing, various cold spray layers were prepared. Spraying with nozzle for inner tube application from two NiCr powders of different particle sizes and from Ni powder of one particle size was applied. In addition, spraying with nozzle type for outer tube applications from same Ni powder was applied too. The evaluation is aimed on mechanical properties and metallographic analysis of cold spray layers as received and after defined heat treatment, comparing small and standard testing specimens. It provide overview of the tensile properties at room temperature and the microstructure of used powders and final cold sprays. Ultimate tensile strength, yield strength, hardness and plastic elongation are evaluated from the mechanical point of view. Metallographic analysis is focused on particle size in powders and splat size in manufactured layers. Porosity of sprayed layers is evaluated on tested specimens and the influence of specimen dimensions is discussed.
