Development of thermocyclic processing modes for carbon steels used on cold forming tools
E3S Web of Conferences, 2023 In this paper, the effect of thermocyclic processing regimes on carbon tool steels used in cold stamping tools is considered. Thermocyclic processing (TCP) is based on the idea of repeated heating-cooling of steels at a temperature different from conventional heating.

Deuterium burning in objects forming via the core accretion scenario - Brown dwarfs or planets?
, 2012 Aims. Our aim is to study deuterium burning in objects forming according to the core accretion scenario in the hot and cold start assumption and what minimum deuterium burning mass limit is found for these objects.

New design of process for cold forging to improve multi-stage gas fitting
Advances in Mechanical Engineering, 2016 This work develops a process that solves the problem of the formation of cracks inside forged gas fittings in the cold forging process that arises from poor forging process design. DEFORM-3D forming software was utilized, and macroscopic experiments with

Influence of the constitutive flow law in FEM simulation of the Radial forging process [PDF]
, 2013 Radial forging is a widely used forming process for manufacturing hollow products in transport industry. As the deformation of the workpiece, during the process, is a consequence of a large number of high-speed strokes, the Johnson-Cook constitutive law (

Forming blocks speed production of strain gage grids [PDF]
, 1965 A tool is designed which facilitates the forming of wire grids used in manufacturing strain gage grids. Flattening the grid wire by a cold working process produces a stabilized grid which can be readily handled for storage or ...

A novel methodology for in-process monitoring of flow forming [PDF]
, 2017 Flow forming (FF) is an incremental cold working process with near-net-shape forming capability. Failures by fracture due to high deformation can be unexpected and sometimes catastrophic, causing tool damage. If process failures can be identified in real

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our
