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

Effect of the Addition of Inorganic Fillers on the Properties of Degradable Polymeric Blends for Bone Tissue Engineering

Molecules
Bone tissue exhibits self-healing properties; however, not all defects can be repaired without surgical intervention. Bone tissue engineering offers artificial scaffolds, which can act as a temporary matrix for bone regeneration.

Effects of residual stress on the flexural strength and microstructure of Al2O3-ZrO2 composites fabricated by different methods

Journal of Materials Science: Materials in Engineering
Due to the mismatch of coefficients of thermal expansion between ZrO2 and Al2O3, thermal residual stress would be induced to the Al2O3-ZrO2 composites during the cooling process. However, Al2O3-ZrO2 composites fabricated by different methods have various
