Process Modeling on Disk Forging

DENKI-SEIKO[ELECTRIC FURNACE STEEL], 2005
Disk-shaped forging parts have been used for a power generation gas turbine and an airplane jet engine. High strength and durability are required for the disks. Therefore, the fine grain and homogenious grain distribution in the disks are very important.

Temperature Monitoring During Forging Process

, 2019
This article deals with the measurement of the thermal behaviour of the mechanical forging press. The forging process is causing thermal changes. The temperature of the forged part can reach 1100 – 1200 °C during the hot forging. Heat transfer is causing thermal deformations of individual parts and it can change clearance in the guidance.

Advancing Electronic Application of Coordination Solids: Enhancing Electron Transport and Device Integration via Surface‐Mounted MOFs (SURMOFs)

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of coordination solids, enabled by the surface‐mounted metal‐organic framework (SURMOF) platform, is on the cusp of generating the organic counterpart of the epitaxy of inorganics. The programmable and sequential SURMOF protocol, optimized by machine learning (ML), is suited for accessing high‐quality thin films of ...

Process Design of Extend Forging Process Using Numerical Simulation Development of Process Design Method for the Finish Forging Process

MATERIALS TRANSACTIONS, 2009
The extend forging process is divided into the initial reduction, performing process (square process) and the finish forging process, and so on. High productivity and dimensional accuracy are desirable features in the finish forging process. In this paper, the relationship between forging conditions and dimensional accuracy was investigated in the ...

Development of the Metal Rheology Model of High-temperature Deformation for Modeling by Finite Element Method [PDF]

, 2019
It is shown that when modeling the processes of forging and stamping, it is necessary to take into account not only the hardening of the material, but also softening, which occurs during hot processing.

Hierarchical Targeting of TREM2+ Myeloid Cells via Acid‐Triggered OMVs Reprogram Immunosuppression and Suppress Osteolysis in Bone‐Metastatic TNBC

Advanced Science, EarlyView.
This study developed a hierarchical targeting nanoplatform, siTREM2@ETP‐PEOz‐OMVs, against triple‐negative breast cancer (TNBC) bone metastasis. It precisely delivers therapeutic siTREM2 to monocytes/macrophages within the metastatic niche. This intervention dually regulates cell fate: reprogramming immunosuppressive macrophages and inhibiting ...
