*Name of journal (for papers), publisher (for books), university and editors (for thesis), conference (for proceedings. ABSTRACT Most metal-forming processes are non-linear, non-stationary and time-variant. Nonetheless, linear controllers or LTI-control systems are used for many of these processes. Because of their simplicity of application, fuzzy controllers have recently been implemented for ...
The effect of heat and strain during the semisolid processing route on microstructural evolution mechanical performance Al-5.5wt%Si-5wt%Zn-0.2wt%Mg alloy was evaluated. as cast heated partially melted to 588 °C (fs = 0.40), thixoformed (in an open die forged) solution heat-treated (SHT) at 525 for 1 6 h. chemical distribution (SEM-EDS) main alloying elements were evaluated each step route. SHT ...
The microstructure plays a crucial role for steel semi-solid forming process, and particularly for the steel thixoforging process, since it determines the thixotropic flow behavior of materials in the semi-solid state. Therefore, it is necessary to well understand the microstructure evolution during high speed heating and forming. Classically, it is investigated on a solid material quenched fro...
application of shearing during solidification to produce a non-dendritic semisolid slurry that can be Semisolid metal (SSM) processing is a relatively transferred directly into a mould or die to give a final new technology for metal forming. Different from product. Thixoforming is used to describe the near the conventional metal forming technologies which use either solid metals (solid state ne...
