Why sex exists? Sex is ubiquitous among living organisms, but the rise of sexual reproduction is a polemic subject in evolutionary biology and no broad consensus has emerged yet. Diverse concepts have been used to explain the ubiquity of sex and its success in biological evolution, but none passed the experimental tests of computer simulations of evolution demonstrating that sexual […]

Charpy impact behaviour of austenitic stainless steel welded joints

Austenitic stainless steels are used in diverse fields such as chemical and petrochemical industries, marine structures, nuclear and agri-food sectors, etc. This is due to their excellent ductility, high notch toughness, corrosion resistance, and good formability. The fusion zone in their welded joints has a duplex structure consisting of austenite and ferrite phases. The ferrite phase has the beneficial role […]
