Weldability of Ferritic Stainless Steel
Abstract: The ferritic stainless steels are generally considered less weldable than austenitic stainless steels. In case of welding of first-generation ferritic stainless steels, rapid grain growth of ferrite takes place in both the fusion zone and heat-affected zone. These coarse grains have very low ductility and toughness. Excessive grain growth can be avoided by using lower welding heat input and or certain types of additives. They are lower in cost and …

Theoretical Analysis of Volume/Weight Fraction of a Dual-Constituent Composite
Abstract: Conventional equations used in analysis of composite materials are modelled based on volume-averaging principle. The volume-averaging equations were re-evaluated to provide an alternative weight-averaging consideration as a result of the difficulty in practical determination of volume fraction of individual constituents of composite material, especially particulate composite. The equivalent weight-averaging equation analysis showed that density plays a significant determining factor in material selection of individual constituent; and composite density evaluated using …
