The objective of this work is the development of Grid-based approaches through which NASA data centers can become active participants in serving data users by transforming archived data into the specific form needed by the user. This approach involves generating custom data products from data stored in multiple NASA data centers. We describe a prototype(More)
Joining titanium alloy and stainless steel is becoming an urgent need since their outstanding mechanical properties can be utilized integratedly. However, direct fusion joining of Ti6Al4V to SS316 can cause brittle Ti-Fe intermetallics which compromise join bonds' mechanical properties. In this research, Laser 3D Printing was applied to explore a new(More)
