Design, microstructure and mechanical properties of new Ti-based alloys
… molecular orbital method three new series of TixFe- yTa, Ti-Fe-xNb and Ti-Nb-xFe alloys are designed for the first time. The alloys are then produced by cold crucible levitation technique. The influence of Ta, Fe and Nb contents on the phase transformation, β phase stability and …

Active metal brazing of alumina to Kovar® using Ag–Cu–Ti-based alloys
… chemical processes leading to the formation of braze joints between alumina of ≥95 wt.% Al2O3 and Kovar® (Fe–29Ni–17Co wt.%) using Ag–Cu–Ti-based active braze alloys (ABAs) have been clarified in this work. In addition, the effects on the resultant microstructure of altering the peak …

In Situ Alloying of Titanium via Laser Powder Bed Fusion
Laser powder bed fusion is a leading additive manufacturing technique capable of producing complex, customised titanium components. However, its broader adoption is constrained by limited commercial alloy options, the high cost of pre-alloyed powders, and pronounced anisotropy arising from coarse …

Investigation of the mechanical properties and phase stability of Ti-transition metal alloys using first-principle calculations
The ternary Ti-X-B (X=Mo/V/Fe/Nb) alloy system has three distinct material classes depending on the fraction of monoboride phase in the Ti-matrix, which makes them useful for broad applications such as aerospace and biomedical fields. Based on the design principle of searching for Ti-monoboride …

Critical stresses for twinning, slip and transformation in shape memory alloys: modeling and experiments
There are four important parameters-(i) transformation stress (ii) twinning stress (iii) austenite slip stress and (iv) martensite slip stress that govern shape memory and superelastic behavior in shape memory alloys (SMAs). However, it is a tremendous experimental effort to determine these …
