Test Method

Adopting the cold metal transfer plus pulse (CMT + P) process, 316L stainless steel wire was treated with a single channel multi-layer deposition experiment under different linear energy. The microstructures of different regions on the deposited samples were observed by optical microscope and scanning electron microscope, and the element distribution in the structure was analyzed by energy dispersive spectrometer. The mechanical properties and microhardness were measured by tensile test method and microhardness tester, respectively, and the anisotropy of tensile strength in horizontal and vertical directions were calculated. Finally, the fracture morphology of the tensile samples were observed by SEM. Experiment results showed that when the difference between the actual and the optimal wire feeding speed matching the specific welding speed was too large, this led to an unstable deposition process as well as flow and collapse of weld bead metal, thus seriously deteriorating the appearance of the deposition samples. The results from metallographic micrograph showed that rapid heat dissipation of the substrate caused small grains to generate in the bottom region of deposition samples, then gradually grew up to coarse dendrites along the building direction in the middle and top region caused by the continuous heat accumulation during deposition. Tensile test results showed that with the increase of linear energy, the horizontal and vertical tensile strength of the as-deposited samples decreased. In addition, the higher linear energy would deteriorate the microstructure of as-deposited parts, including significantly increasing the tendency of oxidation and material stripping. The microhardness values of the bottom, middle and top regions of the samples fluctuated along the centerline of the cross-section, and the values showed a trend of decreasing first and then rising along the building direction. Meanwhile, the yield strength and tensile strength of each specimen showed obvious anisotropy due to unique grain growth morphology. On the whole, the results from this study prove that CMT+P process is a feasible MIG welding additive manufacturing method for 316L stainless steel.

Tensile Strength Test

Concrete is one of the most significant materials in modern society. It is widely used in many projects. Thus it is essential to study the strength and the failure patterns of this material. As well known, the compressive strength is much higher than the tensile strength for concrete. Thus, it is easy to fail due to the tensile strength for concrete. Thus, this paper focuses on the study of the tensile strength of the concrete and its failure patterns. Three types of concretes are made for studying the tensile strengths and the failure patterns of the concretes. Then the Brazilian tensile strength test method is employed in this study. The mythology of calculating tensile strength by the Brazilian tensile strength test method is introduced. Many discs are made for the tests. The Rock mechanics testing machine is used to excavate pressure on the top and bottom of the disc. It is concluded that the failure of the disc is along the vertical diameter between the top and bottom plates contacting the dis. The tensile failure is not obviously influenced by the ratios of the materials while the tensile strength is significantly influenced by the ratios of the concrete. The damage index of concrete is also proposed to describe the capabilities of resisting failure.

Context:The quality of light curing units can profoundly influence mechanical properties of dental composite materials. Aim: To compare effect of Woodpecker RTA Mini-S and Elipar Deep Cure-L curing units onmechanical properties (compressive strength, diametral tensile strength and microhardness) of Filtek Bulk-Fill. Methods and Materials: A total of 32 samples of Filtek Bulk Fill composite were divided into 2 equal groups (n=16). 12 samples in each group were fabricated using a tooth shaped mold and 4 in circular rings to test compressive strength, microhardness and diametral tensile strength, respectively. Theblocks were evaluated for the above parameters using Universal Testing Machine and Vickers Microhardness Tester.Independent sample-t test was used in this study (p< 0.05). Results: The results of this study showed that the group of composites cured using Elipar Deep Cure-L curing unit showed better mechanical properties and the difference between the groups was statistically significant for compressive strength and diametral tensile strength (p < 0.05) Conclusion: It was concluded that a curing unit of higher intensity and quality of output used in conjugation with bulk fill composites are likely to give better results.

The objective of this research to study the impact of v-groove shape on Metal Inert Gas welding procedure of 6mm thickness A6061 aluminum combination and 304 Stainless steel in overlap configuration with welding parameters as; voltage, wire feed rate and shielding gas are 17 volts, 2m/min and 15L/min respectively, the experiment was performed in which the aluminum is upper. 1-mm diameter of ER4042 filler material and pure argon gas as shielded gas. V-groove shapes in steel samples were made with angle 450 . The experiment conducted using SYNERGIC.PRO2 450-4 machine. Tensile test was carried out for each welded sample Universal Testing Machine of MIG welding processes with and without v-grove in steel side. Tensile strengths of welded test samples vary from 15.8 N/mm2 to 26.24 N/mm2 contingents on the welding conditions. The results indicated that v-groove specimens have a maximum strength of tensile strength of 26,24 N / mm2 compared to v-groove samples. It shows the ability to mount inert gas / brazing process aluminum to steel by means of a reversed groove angle and to maximize welding parameters. In conjunction with the half-V-shaped groove the smallest temperature gradient along the steel interface was noted to the smallest difference from top to bottom with IMC thicken values. Tensile test results showed that, owing to its outstanding diffusion behavior of filled filler material, the maximum bonding interface and the correct IMC interface distribution on the steel surface.

In this research, samples of locally manufactured and imported reinforcing steel with different diameters 14 and 16 mm were studied by conducting tensile test, which is an important mechanical test to know the properties of mechanical materials and study their behaviour by under loading two samples of each type using a general tensile testing machine type (SHUMIDUZ –UH2000). The results obtained from this test were used to find a set of properties represented in the ultimate tensile strength (σUTS), yield strength or yield point (σy), yield strain(e), and maximum strain (eMax), and there was a set of properties such as elastic modulus (E), Toughness modulus (T) and modulus of Resilience (Ur) that were mathematically calculated. The real stress and real strain for all samples were calculated too. The engineering stress and the engineering strain were presented by drawing the curves in order to show the difference. The results obtained from the tensile test showed that all samples were of steel reinforcement with protrusions of an average resistance (T30) where the yield stress values were 340-406 N/mm2, and the tensile strength values were 574-673 N/mm2which conforms to the Libyan Standard No. 75 of 2013 for concrete reinforcing steel bars. The results also showed the convergence of local samples with the imported samples.
