Optical microstructure of the full-annealed 1045 steel. Samples for Charpy impact test were machined following the requirement specified in ASTM E 23 (Type A). The Charpy impact tests were performed at room temperature using a standard Charpy pendulum machine with a capacity of 360 . The fracture toughness was estimated from the results of Charpy tests performed on the heat-affected zone (HAZ) of SAE/AISI 1045 steel. In addition, finite element analysis was used to determine the stress state caused by four heavy vehicles (T3-S2-R4 type) localized on one side of the column.Impact test. Measures the ability of a material to absorb a sudden application of a load without breaking. The Charpy test is a commonly used impact test. Lateral expansion. The lateral change in dimension of a Charpy impact specimen due to fracture. The dimension measured is the width opposite the v-notch (see Fig. 1-3).In materials science, the Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture.Absorbed energy is a measure of the material's notch toughness.It is widely used in industry, since it is easy to prepare and conduct and results can be obtained quickly and .
Abstract: The Charpy impact test is a significant tool for the determination of fundamental properties for materials selection in mechanical designs, like the impact toughness and the brittle-ductile transition temperature. Charpy V-notch impact tests on 10 mm thick, Dual-Phase ferrite-perlite steel were evaluated at temperatures ranging from 90 ºC to -60 ºC.Since fracture or failure behavior depends on temperature, Charpy impact tests are often performed in the entire operating temperature range. This shows at what temperature and to what extent the material becomes brittle (tough-to-brittle .The Charpy impact specimens of each material are immersed in a bath for 10 minu tes to reach thermal equilibrium at five separate temperatures ranging from 110oF (-79oC) to 212-oF (100oC). The specimens are quickly transferred to the Charpy testing machine, fractured, and the impact energy is measured. After
The AISI 1045 steel is treated by Annealing (Furnace cooling), Normalizing (room temperature), and Quenching (water). Then the samples were tested for hardness, tensile strength, and toughness (Charpy test). The results show that the tensile strength decreases by 12.4%, 6.33%, and 2.29% in annealing, normalizing, and quenching, respectively.AISI 1045 steel is a medium tensile steel supplied in the black hot rolled or normalized condition. It has a tensile strength of 570 - 700 MPa and Brinell hardness ranging between 170 and 210. . and high strength and impact properties in either the normalized or hot-rolled condition. . AISI 1045 is subjected to forging, annealing .
