MECHANICAL TEST

MECHANICAL TESTING AND METALLURGICAL LABORATORY

The destructive tests that we perform at BOSE are mainly aimed at verifying the surface hardness, the resistance to the different stresses that it may be subjected to, the degree of finish of the machining or the presence of internal cracks in the material.

We have our own workshop and a fleet of machines for Mechanical Tensile Testing, Bending, Breaking (Universal Testing Machine), Shock Bending (Resilience), Brinell Hardness, Rockwell B and C, Vickers, externally calibrated by accredited institutions.

1.1 – BEND TEST

The purpose of the bend test is to evaluate the ductility and/or absence of imperfections on the surface or near the surface of the specimen. This test is applied on metallic materials and welded joints.

1.2 – SHOCK BENDING TESTS

The Charpy resilience is a pendulum that is used in tests to determine the toughness of a material. By using specimens of standardized dimensions with a V-shaped notch, this test also determines the ductile-brittle transition temperature.

The test is performed at laboratory temperature (23 +/- 5ºC), and CHARPY tests can be performed at temperatures of -196ºC.

1.3 – TENSILE TESTS

The test consists of subjecting a specimen to a tensile stress with a constant speed determined by the surface, following the criteria of the standard to be applied, until breakage to determine the following characteristics:

– Tensile strength
– Elastic limit
– Elongation
– Stiffness

This test is carried out for metallic materials without welded joints, in specimens with welded joints and in tubes.

1.4 – HARDNESS TEST

This test is applied to metallic materials and arc welded joints.  The main types of hardness are: Rockwell, Brinell and Vickers, which differ from each other by the type of indenter and by the way the load is applied.

The methods for measuring hardness consist of indenting a sample of the product to be tested by applying a given load on an indenter and then measuring a geometric characteristic of the indentation.

The purpose of these tests is to perform macrographic and micrographic examination of metallic materials for the detection of defects and/or anomalies in the parts to be examined and their microstructure.

2.1 – MACROGRAPHS

The purpose of macrographic analysis is to reveal the macrostructure of a metal or metallic alloy, in order to highlight physical or chemical anomalies likely to affect its homogeneity.

2.2 – MICROGRAPHS

The purpose of micrographic analysis is to reveal the microstructure of a metal or metal alloy by means of a suitable chemical reagent. The attack with the chemical reagent is used to highlight the physical or chemical anomalies likely to affect its homogeneity.

The purpose of Chemical Analysis is to determine the chemical composition of materials. All chemical tests are carried out in the laboratory on all metallic samples susceptible to Chemical Analysis (Iron, Copper, Aluminum and Nickel base) by indication of the Standards to be applied or by customer’s request.
