A Concept to Carry Out a Torsion Test on Components Made of 20CrNiMo2-2 Steel Using Additive Techniques
In recent years, additive manufacturing (AM) technologies, have been one of the fastest developing methods of production of various components. As far as building material is concerned, they allow for using not only polymers, but also composites or metals. Products fabricated using said technologies are used in various areas of industries, for instance in medicine, architecture, entertainment, and in particular in the construction of parts and components of machinery and equipment. To recognize and determine the products’ strength properties in a more comprehensive manner, 3D printing products used in mechanical applications are subject to various tests, e.g. static tensile test. This paper contains research about static torsion test on cylindrical samples made of high grade 20CrNiMo2-2 steel using the selective laser melting (SLM). Such an approach allowed to observe the material behaviour and to determine specific values of strength properties, such as the maximum tangential stresses in the material and bulk modulus of elasticity (shear modulus). The determination of such parameters allowed to compare them with the results of the tests carried out on components manufactured using other methods (e.g. a cold drawn solid bar sample).
