The fatigue resistance of aerospace structures is degraded by the presence corrosion damage. This work characterizes micro-scale (<50 µm) morphologies and underlying microstructure AA7050 that impact crack formation. Corroded specimens were cycled to failure using a fracture surface marking spectrum. Pre-test characterization, fractography EBSD performed. No damage or metric independently corre...

Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...

The performance of components produced by conventional route of a thermo mechanical process and those produced by continuous casting is interesting from different aspects of economy and technology. The performance of products in their service depends on their properties which are strongly influenced by production routes. In the present work the hardness, tensile and tensile-impact behaviors of ...
