Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

Advanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Additive Manufacturing of Highly Alloyed Aluminum–Lithium

Advanced Engineering Materials, EarlyView.
Al–Li alloys, promising for future lightweight constructions due to their low density and high stiffness, are limited to 9 at% lithium in commercial forms because of segregation issues. To overcome this traditional limitation, powder bed fusion with an ultrashort pulse laser is used.

First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

Advanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...

Mechanical Behavior and Microstructural Changes Associated with Tensile Deformation above the Martensite Start Temperature during Quenching and Subsequent Partitioning of a Low‐Alloy 37SiB6 Steel

Advanced Engineering Materials, EarlyView.
A new experimental setup, incorporating digital image correlation and infrared thermography in combination with inductive‐conductive heating for precise temperature control, is used to analyze the mechanical behavior and microstructural changes of sheet metal under complex thermomechanical test conditions that represent quench and partitioning ...
