Revised Semiempirical Approach to Predict the Occurrence of Twinning in Titanium Alloys


2 December, 2021
A revised semiempirical approach, considering the average values of the valence electron to atom ratio (e/a̅) and a difference in atomic radii of alloying element/s and the base element (Δr̅), is proposed to predict the twin formation in titanium alloys. The revised e/a̅ versus Δr̅ diagram is plotted, considering the...Read More

Deformation and toughness behavior of β -type titanium alloys comprising C15-type Laves phase


25 February, 2020
Laves phases are effective in tailoring the mechanical properties of alloys used for structural engineering applications. Therefore, it is an emerging research significance to investigate the deformation features of alloys comprising a Laves phase. In this work, the Ti–33Zr–xFe–yCr (x = 5, 7 wt% and y = 2, 4 wt%) alloys were designed in such a...Read More

Improved trade-off between strength and plasticity in titanium based metastable beta type Ti-Zr-Fe-Sn alloys


26 August, 2019
An impressive strengthening ability of Laves phases is favorable to develop titanium alloys with an improved trade-off between strength and plasticity. Therefore, the Ti-xZr-7Fe-ySn (x = 25, 30, 35 wt% and y = 1, 2 wt%) alloys were first designed in such a manner that a Laves phase would precipitate in these alloys and then the investigated alloys...Read More

Deformation and strength characteristics of Laves phases in titanium alloys


27 May, 2019
The superior reinforcement nature of Laves phases make them suitable for high-strength applications. Therefore, investigations on the deformation and strength characteristics of Laves phases are useful in development of an improved Laves phase-reinforced alloy. In this work, the Vickers micro-indentation method is used to evaluate and compare the deformation and strength characteristics...Read More

Improved deformation behavior in Ti-Zr-Fe-Mn alloys comprising the C14 type Laves and β phases


31 October, 2018
Laves phase alloys are promising materials for several structural applications, but the extreme brittleness is the predominant shortcoming of a Laves matrix. One potential solution to overcome this shortcoming is to alloy Laves matrix with some soft matrix. A group of Ti-35Zr-5Fe-xMn (x = 0, 2, 4, 6, 8 wt%) alloys was cast with an...Read More

High-strength β stabilized Ti-Nb-Fe-Cr alloys with large plasticity


9 July, 2018
A group of Ti-27Nb-7Fe-xCr (x = 0, 2, 4, 6, 8 wt%) alloys were designed on the basis of the DV-Xα cluster method, molybdenum equivalent and valence electron to atom ratio. The designed alloys were produced using the cold crucible levitation melting process for studying their microstructures and mechanical properties. The alloying of Cr renders...Read More

Laves phase precipitation in Ti-Zr-Fe-Cr alloys with high strength and large plasticity


16 May, 2018
In this work, a novel serial of Ti-33Zr-xFe-yCr (x = 3, 5, 7 wt% and y = 2, 4 wt%) alloys was designed first with an expectation to obtain Laves phase in microstructure and then these alloys were produced using cold crucible levitation melting. Microstructure and phase analyses suggest the precipitation of a C15 type Laves...Read More
