Additive manufacturing of strong and ductile Ti–6Al–4V by selective laser melting via in situ martensite decomposition

, 2015
Novel ultrafine lamellar (α + β) microstructures comprising ultrafine (∼200–300 nm) α-laths and retained β phases were created via promoting in situ decomposition of a near α′ martensitic structure in Ti–6Al–4V additively manufactured by selective laser ...

Achieving high-temperature strength and plasticity in near-α Ti-7Al-3Zr-2V alloy using cluster formula design

Journal of Materials Research and Technology, 2022
We here report a Ti-7Al-3Zr-2V alloy, designed following cluster formula approach and prepared by laser additive manufacturing, whose mechanical performance is superior to commonly used Ti-6Al-4V alloy both at as-deposited state and at 600 °C.

Investigation of Cutting Tools and Working Conditions Effects when Cutting Ti-6al-4V using Vegetable Oil-Based Cutting Fluids [PDF]

, 2015
Power consumed in metal cutting is typically converted into heat near the cutting tool edge. Cutting fluids are then provided to a cutting zone in order to improve the tribological characteristics of machining processes and to dissipate the generated ...

Chip formation characteristics of selective laser melted Ti–6Al–4V [PDF]

, 2017
In this research work, chip formation characteristics of selective laser-melted (SLM) Ti–6Al–4V in both ‘as built’ and ‘heat treated’ conditions are studied and compared with conventional wrought Ti–6Al–4V.

Characterization of crack nucleation in TA6V under fretting-fatigue loading using the potential drop technique [PDF]

, 2010
Crack initiation in a Ti-6Al-4V alloy was investigated experimentally in fretting fatigue conditions. A cylinder-plane geometry was used for the contact, and partial slip conditions were considered.

A detailed analysis of the structural, morphological characteristics and micro-abrasive wear behavior of nitrided layer produced in α (CP–Ti), α+β (Ti–6Al–4V), and β (TNZ33) type Ti alloys

Journal of Materials Research and Technology, 2023
The present work aimed to create a hard surface on a titanium surface via plasma nitriding to improve microhardness and wear properties of the as-cast (α-CP-Ti (CP–Ti), α+β-Ti6Al4V (Ti–Al–4V), and β-Ti-33Nb–33Zr (TNZ-33) samples.

In situ tailoring microstructure in additively manufactured Ti-6Al-4V for superior mechanical performance

, 2017
The “Holy Grail” of metal additive manufacturing is to manufacture reliable high-performance metal parts with no or a minimal need of post processing. However, Ti-6Al-4V parts made by selective laser melting (SLM) often suffer from poor ductility and low
