Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

Structural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

Accomplishing Ethics‐Work as a Generic Social Process

Symbolic Interaction, EarlyView.
Existing systems of university research ethics are often criticized by those in the qualitative research tradition. A common thread is that ethics cannot be fully anticipated before the research begins, as is expected by most institutional review boards.

Formation of Distance‐Based Orientation: Political Identity through Relational Positioning in Israel

Symbolic Interaction, EarlyView.
Distance‐based orientation describes how pejorative labels may serve as anchor points for political identity. Existing research on political labeling has largely emphasized stigmatization, overlooking how labels may acquire durability and orienting capacity without losing pejorative force. Drawing on publicly circulating discourse, we trace positioning

Questioning Your Brilliance in Physics: Differential Shifts in Fixed Mindsets by Grade and Gender

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Students' domain‐specific mindsets and their beliefs about their capacity to improve through effort play a crucial role in shaping their experiences and decisions to persist in STEM disciplines. Physics is generally seen as a field requiring innate brilliance, which can reinforce fixed mindsets, particularly after initial setbacks in ...
