Predicting the flow stress behavior of Ni-42.5Ti-3Cu during hot deformation using constitutive equations

, 2013
The hot deformation behavior of ternary Ni-42.5Ti-3Cu alloy was modeled. Hot compression tests were carried out at the temperatures from 800°C to 1000°C and at the strain rates of 0.001 s−1 to 1 s−1.

Constitutive modeling and workability characterization of pre-deformed AZ31 magnesium alloy during hot shear-compression deformation

Journal of Materials Research and Technology
Pre-deformation is a cost-efficient method to control the microstructure and mechanical properties of wrought magnesium (Mg) alloys. It introduces twins that promote dynamic recrystallization during hot deformation, thereby improving hot workability and ...

SPG4 and Dementia: Expanding the Clinical Spectrum

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.

Y Addition Effects on Hot Deformation Behavior of Cu-Zr Alloys with High Zr Content [PDF]

Archives of Metallurgy and Materials, 2018
Isothermal hot compression experiments were carried out using the Gleeble-1500D thermal mechanical simulator. The flow stress of the Cu-1%Zr and Cu-1%Zr-0.15%Y alloys was studied at hot deformation temperature of 550°C, 650°C, 750°C, 850°C, 900°C and the

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Optimization of process parameters of Zy4/TRISO composite using processing maps and breakage rate

Journal of Materials Research and Technology, 2022
Coated fuel particles have been developed into isotropic tristructure (TRISO) for the high-temperature gas reactors. The Zy4/TRISO composite belongs to a Zy4 matrix with distributed coated surrogated nuclear fuel particles (ZrO2 kernel).

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...
