Evaluation of quenched ductile iron mechanical behavior under compressive loads

Abstract

Among the mechanical properties already evaluated in ductile iron, could be mentioned tensile strength, bend, impact Charpy, fracture toughness and fatigue. However, an aspect no longer explored over the mechanical properties of these materials is concerned with the behavior under compressive loads. In this work, compressive properties are evaluated on quenched ductile iron, which is considered at first as an appropriate alternative for mechanical applications with this kind of load. The evaluation was performed by means of compression tests on cylindrical samples. Further application of compressive loads was explored using the tests known as the Brazilian test, which involves the use of a disc compressed along the diameter line. The results obtained are the first attempt of a complete study involving the different choices of ductile iron.
