Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6

Advanced Engineering Materials, EarlyView.
The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

Fabrication of Multifunctional FeSi Gyroid Lattice Composites via Additive Manufacturing and Polymer Infiltration

Advanced Engineering Materials, EarlyView.
A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically

PERFECTIONISM AND ACHIEVEMENT GOAL ORIENTATIONS IN ADOLESCENT SCHOOL STUDENTS

Psychology in the Schools, 2014
Perfectionism has been shown to predict individual differences in achievement goal orientations in university students, but research on perfectionism and goal orientations in school students is still very limited. Investigating 584 adolescent school students in a cross‐sectional correlational design, the present study examined how self‐oriented and ...

Perceptions of classroom goal structures, personal achievement goal orientations, and learning strategies

The Japanese journal of psychology, 2005
We examined the relations among students' perceptions of classroom goal structures (mastery and performance goal structures), students' achievement goal orientations (mastery, performance, and work-avoidance goals), and learning strategies (deep processing, surface processing and self-handicapping strategies).
