Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Design and Performance Study of a Compliant Mechanism Capable of Achieving Dual-Range Constant Force Output

Micromachines
A compliant constant-force mechanism (CCFM), known for its frictionless, contact-free operation and inherently constant output, is typically limited to a single force range, restricting its adaptability to multi-task applications. To address this problem,
