The characteristics of defect bands in the microstructure high pressure die casting (HPDC) AE44 magnesium alloy were investigated. Special attention was paid to effects process parameters during HPDC and structure on distribution bands. Results show that are solute segregation with enrichment Al, Ce La elements, which basically form Al11RE3 phase. There is no obvious aggregation porosities widt...

Background: Creating a socket with proper fit is an important factor to ensure the comfort and control of prosthetic devices. Several techniques are commonly used to cast transtibial stumps but their effect on stump shape deformation is not well understood. This study compares the dimensions, circumferences and volumes of the positive casts and also the socket comfort between two casting method...

The injection of light alloys is an activity that requires a high effort on the part Engineering to maintain its competitiveness. Due temperatures used, wear components connected this manufacturing process quite intense, requiring constant updating effort. This work was developed with view solving problems related excessive nozzles used in die casting process, and corresponding electrical resis...
