Semi-solid metal processing.

Semi-solid processing of tool steel

Semi-solid processing (SSP) of alloys has been used commercially since the early eighties for the manufacture of components in the automobile and aerospace industries. The thrust of the early development has been in aluminium and copper alloys. The nature of the process makes it an ideal candidate for the manufacture of components in alloys which are either difficult or virtually impossible to ...

Revealing the micromechanisms behind semi-solid metal deformation with time-resolved X-ray tomography

The behaviour of granular solid-liquid mixtures is key when deforming a wide range of materials from cornstarch slurries to soils, rock and magma flows. Here we demonstrate that treating semi-solid alloys as a granular fluid is critical to understanding flow behaviour and defect formation during casting. Using synchrotron X-ray tomography, we directly measure the discrete grain response during ...

The T6 Heat Treatment of Semi-Solid Metal Processed Alloy A356

A solution treatment of 1 hour at 540 o C provided the best results for rheocast alloy A356-T6. Natural aging has a significant influence on the subsequent artificial aging response of the alloy. Arrhenius-type equations were derived to predict the time-to-peak hardness as a function of artificial aging temperature.

Semisolid metal processing

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...
