The Effect of Boron on Hot Ductility of Nb-microalloyed Steels

, 2006
Two grades of the Nb-containing steel, one modified with B, were examined in order to study the effect of B on the hot ductility. Since the hot ductility loss of the Nb-containing steel during the continuous casting is manifested as surface cracking, the

Numerical Study of Composite Concrete Castellated Double Channel Beams with Strengthening Techniques

Journal of Engineering
Current numerical research was devoted to investigating the effect of castellated steel beams without and with strengthening. The composite concrete asymmetrical double hot rolled steel channels bolted back to back to obtain a built-up I-shape form are ...

The effect of high temperature deformation on the hot ductility of Nb-microalloyed steel /

, 2004
Low hot ductility at the straightening stage of the steel continuous casting process, where the surface temperature ranges from 600 to 1200°C, is associated with transverse cracking on the billet surface.

A Brief Review on Hot Cracking Austenitic Stainless Steel Welds

Crystals
Hot cracking in welding is a very complex phenomenon. It can happen in the weld metal zone during solidification but also in the heat-affected zone (HAZ). Hot cracking defects are material decohesion that occur at high temperatures along grain boundaries

A special band structure perpendicular to the basal planes formed in a magnesium alloy during hot-rolling process

, 2017
International audienceSpecial band structures were observed in original matrix of AZ31 alloy during hot-rolling process. They were always perpendicular to basal planes, formed by intersecting of -> a + -> c slip on prismatic plane with basal dislocations.

The effect of very high temperature deformation on the hot ductility of a V-microalloyed steel /

, 2008
The loss of hot ductility (HD) of steel during continuous casting is usually attributed to the intergranular precipitation of V and Nb (C, N) as well as segregation of atoms to grain boundaries.
