Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Semi phenomenological modelling of the behavior of TRIP steels [PDF]

open access: yes, 2010
The authors are grateful to ArcelorMittal R&D for supporting this research.A new semi-phenomenological model is developed based on a mean-field description of the TRIP behavior for the simulation of multiaxial loads.

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Progress in Grades and Refining Technology of Ultra Purity Ferritic Stainless Steels

open access: yesTeshugang, 2006
The(C+N)content in ultra purity ferritic stainless steels is ≤150×10-⁶,its corrosion resistance, weldability and toughness are obviously higher than that of common ferritic stainless steels.

Predicting the Ms temperature of lean alloyed ferritic–austenitic stainless steels

open access: yesJournal of Materials Research and Technology
A set of laboratory hot-rolled and thermally cycled 19–22 wt% Cr lean alloyed ferritic–austenitic stainless steels were studied with respect to calculated equilibrium austenite composition and experimental martensite start (Ms) temperature.
