Item PREDICTION OF TENSILE MECHANICAL PROPERTIES OF TIN-BISMUTH ALLOYS BY VICKERS HARDNESS TEST(2022-02-22) Alkilani, Nuri Aburodess Alssid; Şengönül, Cemal Merih; Şimşir, CanerMechanical properties under tensile are the most fundamentally used ones to predict the mechanical behavior of materials. However, the tensile test can be a cumbersome method concerning its bulky equipment, detailed sample preparation protocols and considerably high cost. Since there is a strong relation between hardness and tensile strength of the materials, there are some research studies aimed to establish a correlation between the tensile properties and hardness values of a material. In fact, hardness measurement is mostly a trivial process which can be performed without complicated protocols to get information about a material in an apparently cheap and fast way by using small-scale benchtop instruments. In this research work, we adopted similar approach to attain an analytical relationship between mechanical properties like tensile strength, yield strength, strain hardening exponent and strength coefficient of a low melting point alloy system, tin-bismuth (Sn-Bi) and their Vickers hardness numbers. This thesis covers a comparative analysis of data from hardness and tensile tests to develop a mathematical relationship that will predict the stress-strain behavior of these alloys, particularly eutectic. Hence four different compositions of the Sn-Bi alloys are used with Bi percentages such as 30%, 40%, 50% and 57% in this work. Tensile tests were performed at room temperature and their plastic regions up to UTS were analyzed to determine the aforementioned mechanical properties of the given alloy compositions. Concurrently hardness measurements were performed to obtain their Vickers hardness numbers. As a result, we determine a strong relationship between the tensile mechanical properties and the hardness of the Sn-Bi alloy and the established numeric model predicted most of the mechanical properties with a high statistical significance.
