Spinodal decomposition stabilizes plastic flow in a nanocrystalline Cu-Ti alloy [PDF]

arXiv, 2021
A combination of high strength and reasonable ductility has been achieved in a copper-1.7 at.%titanium alloy deformed by high-pressure torsion. Grain refinement and a spinodal microstructure provided a hardness of 254 +/- 2 HV , yield strength of 800 MPa and elongation of 10%.

Geometry‐Assisted Phase Selection: Interplay of Phase Heterogeneity and Geometry in Gyroid Shell Metamaterials Printed with 17‐4 PH Stainless Steel

Advanced Engineering Materials, EarlyView.
This study explores geometry‐driven phase evolution in gyroid shell metamaterials made via laser powder bed fusion of 17‐4 precipitation hardened stainless steel. Locally hardened regions develop along the primary loading paths in the structure, which finite element analysis and geometric considerations link to enhanced gyroid strength.

Machinability of Titanium Alloys.

JSME International Journal Series C, 2003
Titanium and its alloys find wide application in many industries because of their excellent and unique combination of high strength-to-weight ratio and high resistance to corrosion. The machinability of titanium and its alloys is impaired by its high chemical reactivity, low modulus of elasticity and low thermal conductivity. A number of literatures on

Effects of Creep in Titanium at Room Temperature during Tensile and Profilometry‐Based Indentation Plastometry Testing

Advanced Engineering Materials, EarlyView.
This article concerns room temperature tensile testing, with a range of (nominal) strain rates, of three titanium alloys. Stress–strain curves are analyzed to obtain creep characteristics. Profilometry‐based indentation plastometry testing is also covered, using different penetration velocities, and correlations established with tensile data.

Laser surface nitriding of titanium and a titanium alloy

Journal of Materials Processing Technology, 1992
Surfaces of titanium and titanium alloy IMI829 have been nitrided by laser melting in nitrogen and in a gas mixture containing various proportions of argon and nitrogen. The nitrided layers have been characterised with respect to their hardness, microstructure, chemical composition, corrosion properties and surface finish.
