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.

Novel Surface‐Based Bézier Metamaterials: A Higher Degree of Parametrization toward Tailoring the Effective Properties under Compression

Advanced Engineering Materials, EarlyView.
Cubic Bézier curves are used in the synthesis of novel surface‐based metamaterials with tunable mechanical properties. Surface‐based geometries are 3D printed and tested in compression. The resulting mechanical properties are correlated to changes in the shape of the base curve, with high potential in energy absorption through the adjustment of their ...

Boundary conditions applied on bearing corner in direct aluminum extrusion [PDF]

, 2009
Finite element analysis in aluminum extrusion is faced by several problems such as number of degrees of freedom, calculation time, large deformation and flow conservation. The problem of large deformation is overcome by applying the Eulerian formulation.

The Effect of Thickness, Build Orientation, and Loading Rate on the Tensile and Compressive Properties of Selective Laser Sintering Polyamide 12 Specimens

Advanced Engineering Materials, EarlyView.
This article examines how build orientation, thickness, and loading rate affect the tensile and compressive properties of LS‐manufactured polyamide 12 12 parts. Through over 120 experiments, it reveals strong ductility anisotropy in tension, minimal compressive sensitivity, and significant thickness and strain rate dependencies.

Impact of Various Rotary Friction Welding Process Parameters on the Mechanical Properties of a Steel–Aluminum Joint

Advanced Engineering Materials, EarlyView.
Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

Advanced Engineering Materials, EarlyView.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via
