Pressure die casting is the most used process for producing structural parts for the metalworking sector. It uses alloys with a eutectic composition and high iron content, generating parts with good mechanical properties but relatively high porosity and shrinkage voids, between 2 and 5%. Processing in the semisolid state (SSM) reduces the number of defects to less than 1% by practically e…
In this research project we intend to study the processing in the semisolid state of new materials (Al-Ti-(Zn-Cu-Mg), as well as the mechanical properties, resistance to wear and corrosion. The alloys designed with the aid of computational tools (Calphad) will be obtained in resistive electric furnaces of 9.6 and 12kW of power. Later they will be processed in the semi-solid state via: Rec…
The processing of metallic alloys in the semi-solid state, (SSM or S2P), is nothing more than the forming of materials in the mushy state. Among the main processes, Rheocasting and Thixoforming stand out, which compete with die-casting technology (permanent mold injection) and with hot forging operations (in open or closed die). Metal alloys of the Al-Si and Mg-Al system are commercially …
The present proposal aims to provide the Laboratory of Foundry and Thixoforming of the School of Mechanical Engineering / Unicamp of a cold chamber injection die casting machine for aluminium alloys, which will provide the manufacturing of cast, rheocast or thixoformed parts. The main objective is to accelerate the development, processing and mechanical and microstructural characterizatio…

This project aims to study the thixoformability, ie, the potential for applications in thixoforming processes of hipoeutectic cast iron modified by chromium, with the basic composition Fe-2,5wt%C-Xwt%Cr-1%,5wt%Si. Alloys containing chromium content of 0, 2, 4 and 6wt%Cr, will be manufactured and donated to the project by the company IMBIL - Industry and Maintenance of Pumps Ltd. ITA., Acc…
There are few commercial alloys available for processing in the semi-solid state, notably the A356 and A357 alloys, both based on Aluminium-Magnesium-Silicon system. In recent projects, it was developed new alloys in the aluminum-silicon-copper system which generated seven patents (four international: BR200805448-A2, BR200805449-A2, A2-BR200805450, BR200805451-A2). The Foundry Laboratory …
This project aims to deepen the development of technology for obtaining and characterisation of new metal alloys for applications in the semi-solid state. In recent work, it was mapped the influence of the silicon and magnesium content in obtaining as well as in the viscous behaviour of some Al-Si-Mg alloys, produced by semi-continuous casting with and without electromagnetic stirring, (w…
The proponent of this internship abroad has worked in recent years on the thermodynamic aspects of the development of new alloys for use in processing in the semi-solid state, as well as performing metallurgical and microstructural evaluation work in such alloys. However, this research field needs to be deepened in the sub-area of evaluation of the rheological behavior of such slurries, c…
In the last years cast irons have been proved as potential raw materials for semisolid processing presenting favorable skills such as good fluidity and stability at the semisolid state. New Fe-2.5C-xCr-1.5Si alloys (where x is 3, 5 and 7Cr) have been evaluated in a doctoral study in progress (FAPESP 2011/19997-0) as a potential semisolid raw material and preliminary results pointed to low…
