“…In considering the plastic deforma-tion of materials having notch and cracks, 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. This absorbed energy (the Charpy impact energy) is related to the area under the total stress-strain curve and is a measure of a given material's toughness and acts as a tool to study temperature-dependent brittle-ductile transition [26]. One can expect that materials with large values of strength and ductility to have large Charpy impact energy.…”

In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, the effect of a notch on impact behavior was examined by conducting the Charpy tests on borided and unborided steels. The greatest notch toughness was found for a steel AISI 316 with a microstructure consisting of different C, Ni and Cr chemical composition compared to AISI 1040, 1045 and 4140 steels.

“…In the upper samples, a large part of the notch length was located in the last deposited bead, while the middle and lower samples contained a mixture of differently reheated material. Three samples were tested at each temperature according to DIN EN ISO 148-1, and the measured values were converted to the values for a 10 × 10 mm 2 sample by applying a geometric factor accounting for the size of the fractured area compared to a standard size sample [14].…”

Influence of inhomogeneity on several length scales on the local mechanical properties in V-alloyed all-weld metal

Recently, a new, vanadium alloyed welding consumable with a minimum yield strength of 1100 MPa was developed. The mechanical properties of welding consumables for gas metal arc welding are usually classified by producing and testing allweld metal samples, which are typically a multipass weld. Chemical and microstructural fluctuations of a vanadium alloyed allweld metal sample on a macro-and microscale and their influence on the local mechanical properties were investigated. On a macroscale, hardness mappings show a pattern of hard and soft zones which can differ up to 60 HV. Despite the existence of these fluctuations, undersized Charpy V-notch tests revealed no significant difference between the last weld bead and the underlying ones. It is explained how vanadium and its tendency to form precipitates affect both the hardness inhomogeneity and the toughness homogeneity. On a microscale, segregations of several alloying elements and significant grain size fluctuations were found. Their influence on fluctuations of the mechanical properties is discussed as well.
