Residual Stress Measurements of Cast Aluminum Engine Blocks Using Diffraction
Residual stresses and strains in as-cast and annealed aluminum engine blocks were mapped in the main web area above the bearing split using diffraction. Automated coordinate-mapping of the surface and bulk strains was accomplished with X-ray and neutron diffraction, respectively. LabVIEW-based software was developed for improved efficiency, flexibility and quality of data analysis. In the hoop ...
متن کاملSimulation and modeling of friction welding of stainless steel to aluminum alloy using finite element method and artificial neural network
Aluminum to stainless steel joints are broadly used in industries in order to reduce fuel consumption. While fusion welding is not a suitable method to join these metals. solid state welding, like friction welding (FW), is an effective way to this process. However, risk of intermetallic compounds (IMCs) formation is probable in these welds. In previews investigations formation of FeAl3, Fe2Al5 ...

متن کاملX-Ray and Neutron Diffraction Measurements of Dislocation Density and Subgrain Size in a Friction-Stir-Welded Aluminum Alloy
The dislocation density and subgrain size were determined in the base material and friction-stir welds of 6061-T6 aluminum alloy. High-resolution X-ray diffraction measurement was performed in the base material. The result of the line profile analysis of the X-ray diffraction peak shows that the dislocation density is about 4.5 9 10 m 2 and the subgrain size is about 200 nm. Meanwhile, neutron ...
متن کاملCast Aluminum Alloy for High Temperature Applications
Originally developed by NASA as high performance piston alloys to meet U.S. automotive legislation requiring low exhaust emission, the novel NASA alloys now offer dramatic increase in tensile strength for many other applications at elevated temperatures from 450°F (232°C) to about 750°F (400°C). It is an ideal low cost material for cast automotive components such as pistons, cylinder heads, cyl...
