Characterization of the austenite recrystallization by comparing double deformation and stress relaxation tests [PDF]
, 2010 A high amount of deformation below the non-recrystallization temperature (T-nr) is a common industrial practice to achieve a good combination of toughness and strength in microalloyed steels.

Broadband dual-frequency comb spectroscopy in a rapid compression machine
Optics Express, 2019 We demonstrate fiber mode-locked dual frequency comb spectroscopy for broadband, high resolution measurements in a rapid compression machine (RCM). We apply an apodization technique to improve the short-term signal-to-noise-ratio (SNR), which enables broadband spectroscopy at combustion-relevant timescales. We measure the absorption on 24345 individual

Influences of the end of injection and ambient temperature on biodiesel combustion
Journal of Mechanical Engineering and Sciences, 2017 Influence of the injection pressure and ambient temperature at the end of injection of biodiesel spray has been studied using Rapid Compression Machine (RCM). The experiments were conducted on a RCM for the premixed combustion with a single injection at

Effects of ambient temperature and injection pressure on biodiesel ignition delay
Journal of Mechanical Engineering and Sciences, 2017 Biodiesels are promoted as alternative fuels due to their potential to reduce dependency on fossil fuels. The main problem in diesel combustion chamber design is to understand the importance of interaction phenomenon between fuel spray and surrounding ...

The mechanical behaviour of an ultrafine grained Ti-47Al-2Cr (at%) alloy in tension and compression and at different temperatures [PDF]
, 2011 A bulk ultrafine grained (UFG) Ti-47Al-2Cr (at%) alloy has been produced using a powder metallurgy process that combines high energy mechanical milling (HEMM) of a mixture of Ti, Al and Cr powders to produce a Ti/Al/Cr composite powder and hot isostatic ...

Observation of Damage Growth in Compressively Loaded Laminates [PDF]
, 1983 An experimental program to determine tie phenomenological aspects of composite-panel failure under simultaneous compressive n-plane loading and low-velocity transverse impact [C-75 m/s (0-250 ft/s)] is described.

Constrained hyperbolic divergence cleaning in smoothed particle magnetohydrodynamics with variable cleaning speeds [PDF]
, 2016 We present an updated constrained hyperbolic/parabolic divergence cleaning algorithm for smoothed particle magnetohydrodynamics (SPMHD) that remains conservative with wave cleaning speeds which vary in space and time. This is accomplished by evolving the
