Simulating semi-solid metal forming requires modelling of semi-solid behaviour. However, such modelling is difficult because semi-solid behaviour is thixotropic and depends on the liquid–solid spatial distribution within the material. In order to b

The paper presents the results of an experimental investigation, done on the friction stir welding (FSW) plunging stage. Previous research works showed that the axial force and torque generated during this stage were characteristic for a static quali

Tolerance verification permits to check the product conformity and to verify assumptions made by the designer. For conformity assessment, the uncertainty associated with the values of the measurands must be known. The Guide to the Expression of Uncer

The purpose of functional tolerancing process is to define the geometrical specifications (tolerances) of parts ensuring functional requirements. An important distinction in tolerance process is that engineers are more commonly faced with the problem

The deformation process of steel in the semi-solid state, or thixoforming is an alternative solution to the classical industrial processes that are the casting or the hot forging. Thixoformed steel parts are of better quality and may substitute advan

The pre and post treatment of the thixoformed parts in terms of heating conditions and controlled cooling has a great influence on the final microstructure and the properties of the parts and their homogenization. The paper presents recent investigat

Forming of parts in the semi-solid state is quite a complex process, especially for high melting point alloys such as steel. A reason for this complexity is the amount of parameters involved in the process. Among these we could quote liquid fraction,
