Prediction of FV520B Steel Flow Stresses at High Temperature and Strain Rates

High Temperature Materials and Processes, 2015
In order to develop reliable constitutive equations for the simulation, the hot deformation behavior of FV520B steel was investigated through isothermal compression tests in a wide range of temperatures from 900 °C to 1100 °C at an interval of 50 °C and ...

Effect of nitrogen content on the hot deformation behavior of 0Cr16Ni5Mo martensitic stainless steel

工程科学学报, 2017
The hot deformation behavior of 0Cr16Ni5Mo martensitic stainless steel with different nitrogen contents was studied on a Gleeble3800 thermal machine. The true strain-stress curves and deformed microstructures of the tested steels were investigated.

FE implementation of damage-coupled inelastic constitutive equation for P91 steel

Mechanical Engineering Journal
The objective of this study is to numerically evaluate the cyclic softening behavior and creep-fatigue damage of P91 steel. To achieve this, a damage-coupled inelastic constitutive equation is formulated by coupling the Chaboche-type viscoplastic ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
