Low-temperature impact toughness and deformation mechanism of CT20 titanium alloy

Lei Lei et al.

Summary: This study investigates the impact toughness and deformation mechanism of near-alpha-type low-temperature titanium alloy CT20 at different temperatures. It is found that CT20 exhibits high impact toughness at 20 degrees C, but brittle fracture occurs at -196 degrees C. The tortuous crack path, dislocation slip, and deformation twinning synergistically contribute to the high impact toughness at 20 degrees C, while the plastic deformation capacity decreases significantly at -196 degrees C.

In Situ SEM Investigation of Deformation Processes and Fracture Behavior in Bimodal Ti-6Al-3Nb-2Zr-1Mo Alloy

Haisheng Chen et al.

Summary: The deformation mechanism, crack initiation, propagation, and fracture behavior of a new near-alpha titanium alloy Ti80 (Ti-6Al-3Nb-2Zr-1Mo) are studied through in situ tensile testing in SEM. It is found that alpha(p) grains undergo plastic deformation (single slip) initially, and cracks tend to initiate at the alpha(p)/beta(trans) interface and slip bands region. However, slip transfer and multi-slip/cross-slip in alpha(p) delay crack initiation. During crack propagation, the crack tends to follow the path along the alpha(p)/beta(trans) interface or slip bands inside alpha(p), with the alpha(p) boundaries deflecting the crack propagation direction.

Alloys-by-design: A low-modulus titanium alloy for additively manufacture d biome dical implants

E. Alabort et al.

Summary: This study utilizes an alloy design approach to identify biocompatible titanium alloy compositions with a lower modulus of elasticity than the commonly used Ti-6Al-4V grade. The study also considers the additive manufacturability of the alloys and identifies compositions with low cracking susceptibility and propensity for non-planar growth. An optimal alloy composition is selected for selective laser melting, resulting in an engineered microstructure with outstanding combined strength and ductility.

High-strength titanium alloys for aerospace engineering applications: A review on melting-forging process

Qinyang Zhao et al.

Summary: High-strength titanium alloys (HS-TAs) are crucial structural materials for advanced engineering applications. Achieving the synergy of high strength, high ductility, and high toughness has been identified as a technical bottleneck. Two primary strategies, developing novel alloys and innovating processing technologies, have been initiated to overcome this challenge. This review provides an overview of the research status, processing and heat treatment technologies, phase transformation, processing-microstructure-property correlation, and strengthening-toughening mechanism of HS-TAs for aerospace engineering applications.

A strain rate and temperature-dependent crystal plasticity model for hexagonal close-packed (HCP) materials: Application α-titanium

Liansong Dai et al.

Summary: This study proposes a novel crystal plasticity model to describe the mechanical behavior and microstructure evolution of HCP materials. A new flow rule is developed to incorporate the effects of strain rate and temperature on the activation of specific deformation mechanisms. Numerical simulations show that increasing strain rate or decreasing temperature promotes twinning over slip, resulting in more pronounced hardening and higher stress levels.

Impact toughness and deformation modes of Ti-6Al-4V alloy with different microstructures

Lei Lei et al.

Summary: The impact toughness of Ti-6Al-4V alloy with different microstructures was studied, with the bimodal microstructure (BM) showing the highest impact toughness due to a composite-like structure containing hard primary alpha grain and soft beta transformation microstructure. In contrast, the fine and coarse lamellar microstructures (LM1 and LM2) exhibited lower impact toughness due to limited plastic deformation and heterogeneous deformation, respectively. Coordination of deformation abilities within the microstructure was found to play a key role in impact toughness of the alloy.

Shear localization in metallic materials at high strain rates

Na Yan et al.

Summary: The development of adiabatic shear localization is governed by three factors: strain hardening (or softening), strain-rate hardening, and thermal softening. In metallic materials, the formation and evolution of adiabatic shear bands at the nano and micro scale are associated with the transformation of grains, and modern experimental and computational techniques provide a deeper and predictive understanding of this phenomenon.
