Non‐Destructive and Mechanical Characterization of the Bond Quality of Co‐Extruded Titanium‐Aluminum Profiles

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

The Economic Argument for Cleaning Up the Chesapeake Bay and its Rivers [PDF]

open access: yes, 2012
Failure to "Save the Bay" threatens the Bay's value as an economic driver. Conversely, investing in clean-water technology creates jobs, generates economic activity, and saves money in the long run. Hence, the protection and restoration of the Chesapeake

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?

open access: yesAdvanced Engineering Materials, EarlyView.
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Clean Air, Clean Water, Clear Conscience [PDF]

open access: yes, 2021
Humans can survive a few minutes without access to air, a few days without water, and a few weeks without food. Even with access to these commodities, if they are contaminated then humans will suffer health problems. This chapter provides insights into the historical context for the eventual development of, and the recognized need for, clean water and ...

Development of a Novel Processing Route for Dispersoid/Precipitation‐Strengthened High Conductive Copper Alloys by Using Metalized Nanoceramics in Additive Manufacturing

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.
