Warm forming of 7075 aluminum alloys
Procedia Engineering, 2017 Abstract The paper presents forming results of the drawpiece made of T6 temper 7075 aluminum alloy. The development of new, state-of-the-art forming methods by scientific and research centers is mainly driven by increasing demand for lightweight construction materials characterized by superior mechanical properties. As an example, new forming methods

Warm Electrohydraulic Forming: A Novel High Speed Forming Process
Procedia Engineering, 2017 Abstract Electrohydraulic forming (EHF) is one of the high speed forming processes for sheet metals which has considerable effect on formability improvement. In this process, the electrical energy stored in a bank of capacitors, discharges between a pair of electrodes submerged in a fluid and forms the sheet metal.

Analysis of Springback Characteristics of Magnesium Alloy Sheet (AZ31B) Considering Time-Dependence in Warm Bending [PDF]
한국정밀공학회지, 2020 The purpose of this study was to investigate the springback behavior of magnesium alloy (AZ31B) at high temperature with respect to the holding time in the die-set. The changes of microstructure in the springback during V-Bending were analyzed.

Cyst-forming dinoflagellates in a warming climate [PDF]
Harmful Algae, 2020 Many phytoplankton species, including many harmful algal bloom (HAB) species, survive long periods between blooms through formation of benthic resting stages. Because they are crucial to the persistence of these species and the initiation of new blooms, the physiology of benthic stages must be considered to accurately predict responses to climate ...

Journal of materials engineering and performance (Print), 2023 Warm forming has been shown to be an effective way to increase the formability of various aluminum sheet alloys. If applied to precipitation hardenable alloys, aging and/or coarsening may occur during heating and/or forming processes. As such, there is a

A WARM MODE OF GAS ACCRETION ON FORMING GALAXIES [PDF]
The Astrophysical Journal, 2012 We present results from high--resolution cosmological hydrodynamical simulations of a Milky--Way-sized halo, aimed at studying the effect of feedback on the nature of gas accretion. Simulations include a model of inter-stellar medium and star formation, in which SN explosions provide effective thermal feedback. We distinguish between gas accretion onto

Two step–ageing of 7xxx series alloys with an intermediate warm-forming step
, 2021 Two-step ageing of 7xxx series alloys can reduce ageing time while obtaining similar mechanical properties as a longer isothermal heat treatment. In this paper, an intermediate deep-drawing step at 120–160 °C is introduced to produce elongated cup–shaped
