One of the most dangerous technical failures of materials is intergranular brittle fracture
(temper embrittlement) as it proceeds very quickly and its appearance is often hardly …

The character and distribution of grain boundaries (GBs) in molybdenum materials and their
decoration with solutes may lead to strengthening or weakening effects which limits the …

A complete classification of [100] tilt grain boundaries into the categories of special, vicinal
and general resulting from measurements of grain boundary segregation in α-iron is …

Starting with a fairly comprehensive database on experimental results on enthalpy and
entropy of grain boundary segregation, the detrimental influence of ignoring the segregation …

The segregation behaviour of a cation (yttrium) with a low solubility in the polycrystalline
oxide host (α-Al 2 O 3) has been investigated at temperatures between 1450 and 1650° C …

Segregation-induced changes in interfacial cohesion often control the mechanical
properties of metals. The change in the work of separation of an interface upon segregation …

The present research work explores the joints of various dissimilar metals produced by
ultrasonic spot welding. The weld strength, interface temperature, weld area and …

Ultrasonic spot welding (USW) is an energy efficient thermomechanical technology causing
effective bond in less than a second for difficult dissimilar materials combination such as …

The H–Fe interaction at a grain boundary (GB) in BCC Fe was studied using qualitative
electronic structure calculations in the framework of the atom superposition and electron …

We thoroughly compare available experimental as well as theoretical values of the
strengthening/embrittling energy of numerous solutes at grain boundaries in α-iron and …
