Among the various damages that are subject to hot work tools, thermal fatigue figure as one of the most common failure mechanisms for the initiation of cracks. Thermal fatigue can be defined as a gradual deterioration and eventual cracking of material by alternating heating and cooling, during which the free thermal expansion is partially or completely constrained. In order to extend the …

High hardenability of steels during quenching requires low severity quenchants since the presence of alloying elements can promote martensitic transformation. However, those alloying elements increase the cost of the steel and the use of high severity quenchants can give good properties even for plain carbon steels. So, this work is proposing the use of very high severity quenchant to que…
The goal is analyze mechanical properties of the steel AISI 1045 after intensive quenching using as quenchant: nanofluids (SiO2 e ZnO2) and saline solutions (NaNO2 e NaHCO3). It will be performed tests of tensile strength, residual stress and fracture toughness. For toughness it will be used an alternative method used by IMT, Slovenia which is made with tensile strength test and notched c…
In the manufacturing industry, it's trivial to use steels tools. Those alloys, called tool steels, are special alloys designed for working on other materials. The tooling industry is increasingly demanding improvement in the tools' quality, i.e., longer lifetime and lower costs of the tools. The mechanical and metallurgical tools' properties are directly related to, which, heat treatment …

The spring steels are the materials most commonly used in car suspensions and are subject to heavy efforts in terms of load, impact and also under intense fatigue solicitation. Required mechanical performance depends mainly on the chemical composition and heat treatments. After a year of research funded by FAPESP, important results have been achieved showing the influence of cryogenic tre…
