Projeto, construção e validação de aparato Jominy, segundo norma ASTM A255-02

Abstract

This work aimed to design and build a Jominy test equipment. The Jominy test is intended to determine the temperability of the materials. To do so, it was initially done a survey of data on the concept of temperability, from the steel microstructures to the Jominy test. Next, the sizing and construction of the apparatus was carried out, taking into account materials and ease of construction. To validate the project we needed tests that generate tempera- ture curves that match existing literary data. Therefore, after the construction, the test was carried out with the equipment, followed by the measurement of hardness of the specimens and comparison of the tempera- ture curves generated with data present in the literature to validate the built equipment. Thus, the Jominy test apparatus constructed allowed the obtaining of data consistent with the literature, which allowed to validate it.
