Antimicrobial Titanium–Copper Alloys: The Role of Microstructure in Arc‐Melted Compositions

Advanced Engineering Materials, EarlyView.
Copper‐containing titanium alloys show promise in combating orthopedic implant infections. This study explores the influence of heat treatment on Ti‐11.5Cu and Ti‐33Cu alloys, revealing that larger Ti2Cu precipitates (≈5 μm) enhance antimicrobial efficacy through increased surface contact. Results suggest contact sterilization is the primary mechanism,

The Crystallography of Aluminum and Its Alloys [PDF]

, 2019
This article begins with pure aluminum and a discussion of the form of the crystal structure and different unit cells that can be used to describe it. Measurements of the face-centered cubic lattice parameter and thermal expansion coefficient in pure aluminum are reviewed and parametrizations are given which allow the reader to evaluate them across the

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

Advanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Age-hardening of high pressure die casting AlMg alloys with Zn and combined Zn and Cu additions

Materials & Design, 2019
This study investigates the age-hardening of AlMg alloys with Zn and combined Zn and Cu additions. Two AlMg5Mn1 alloys modified with Zn and Cu were processed by high pressure die casting (HPDC) and different heat treatment strategies.

CALPHAD‐Guided Prediction and Interpretation of Phase Formation in Ta–Mo–Cr–Ti–Al Refractory High‐Entropy Alloys

Advanced Engineering Materials, EarlyView.
This study designs Ta–Mo–Cr–Ti–Al refractory high‐entropy alloys with a disordered body‐centered‐cubic A2 crystal structure aiming for improved ductility, lower density, and oxidation resistance. Four alloy compositions are identified by thermodynamic calculations.

Fatigue strength of aluminum and aluminum alloys

Journal of Japan Institute of Light Metals, 1973
The effect of high pressure solidification on the fatigue strength of cast aluminum and aluminum alloys was studied.(1) The fatigue limit of pure aluminum is hardly influenced by high pressure solidification.(2) High pressure casting of an eutectic Al-Si alloy (JIS AC3A and AC4C)(3) The fatigue limit of an Al-Cu alloy (AC1A), T-6 treated, is increased ...

Influence of Heat Treatment on Microstructure and Mechanical Properties at Elevated Temperatures of Nonweldable Ni‐Based Alloy Printed by Fused Filament Fabrication

Advanced Engineering Materials, EarlyView.
The fused filament‐fabricated MAR‐M247 alloy without hot isostatic pressing shows the lowest porosity of 4%. Heat treatment at 1220 °C produces coarse precipitates and carbides. Specimens heat‐treated at 1220 °C exhibit higher tensile strength (683 MPa) and elongation (10%) at room temperature.
