Warm Spray Forming of Ti-6Al-4V [PDF]

open access: yesJournal of Thermal Spray Technology, 2013
Warm spray (WS) is a modification of high-velocity oxy-fuel spraying, in which the temperature of the supersonic gas flow generated by the combustion of kerosene and oxygen is controlled by diluting the combustion flame with an inert gas such as nitrogen.

The Far-Ultraviolet Spectra of TW Hya. II. Models of H2 Fluorescence in a Disk [PDF]

open access: yes, 2004
We measure the temperature of warm gas at planet-forming radii in the disk around the classical T Tauri star (CTTS) TW Hya by modelling the H2 fluorescence observed in HST/STIS and FUSE spectra.

Warm gas towards young stellar objects in Corona Australis - Herschel/PACS observations from the DIGIT key programme [PDF]

open access: yes, 2013
The effects of external irradiation on the chemistry and physics in the protostellar envelope around low-mass young stellar objects are poorly understood. The Corona Australis star-forming region contains the R CrA dark cloud, comprising several low-mass

Investigation of the Flow Behaviour of Martensitic Steel at Elevated Temperatures Via Uniaxial Tensile Tests [PDF]

open access: yesArchives of Metallurgy and Materials
In recent years, advanced high strength steels have been the main choice of automobile manufacturers due to their excellent strengths and decent formability. In this study, the forming behaviour of a martensitic steel (MART 1200) at elevated temperatures,

The chemistry of C3 & Carbon Chain Molecules in DR21(OH) [PDF]

open access: yes, 2012
(Abridged) We have observed velocity resolved spectra of four ro-vibrational far-infrared transitions of C3 between the vibrational ground state and the low-energy nu2 bending mode at frequencies between 1654--1897 GHz using HIFI on board Herschel, in ...

Constitutive model and compaction equation for aluminum alloy powder during compaction

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
The deformation mechanisms in powder compaction can be described by a constitutive model, which is the cornerstone for modeling the powder compaction process by finite element simulation.

Warm Electrohydraulic Forming: A Novel High Speed Forming Process

open access: yesProcedia 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.

Investigation on the effect of pressure rate on formability of aluminum alloy during warm/hot sheet hydroforming

open access: yesAIP Advances, 2018
Warm/hot sheet bulging tests of 2A16-O aluminum alloy were conducted using elliptical bulging dies under various temperatures and pressure rates, in an effort to investigate the macroscopic and microscopic influence of the pressure rate on the ...
