INVESTIGATION OF THE HEATING TEMPERATURE INFLUENCE ON MECHANICAL CHARACTERISTICS AND DEFORM ABILITY OF STEEL OF TYPE 18HG AT NON-FULL HOT DEFORMATION

Литьë и металлургия, 2006
Steel forming technology in conditions of warm forming is a process, which is very attractive for technological practice in term of lower energy consumption, higher quality of the surfase and dimensional precision of gorged pieces.

The Influence of Heat and Holding Time on the Warm Forming of Al–Mg–Si Alloys

Journal of Manufacturing and Materials Processing
Warm forming of heat-treatable aluminium alloys can induce significant changes in their initial heat treatment, affecting both the forming process and the final in-service properties.

Warm-forming of pre-aged Al-Zn-Mg-Cu alloy sheet

Materials & Design, 2020
Aluminium alloys of the 7xxx series are attracting the attention of automakers due to their high specific strength. However, widespread use of 7xxx series alloys for the production of car parts from sheet metal has so far been prevented due to their low ...

Starburst Driven Galactic Superbubbles Radiating to 10 K [PDF]

, 2016
Our three-dimensional hydro-dynamical simulations of starbursts examine the formation of superbubbles over a range of driving luminosities and mass loadings that determine superbubble growth and wind velocity.

Synthesis of a Novel Thermoresponsive S53P4 Bioactive Glass Extract–Poloxamer 407 Injectable Hydrogels: Assessment of Biocompatibility and Antimicrobial Properties

Advanced Engineering Materials, EarlyView.
This study investigates innovative thermoreversible hydrogels derived from S53P4 bioactive glass extracts to aid in the healing of infected diabetic foot wounds. These injectable gels, which gel at body temperature, release beneficial ions and remain stable over time.

Influence of an Oxygen‐Free Atmosphere on Diamond‐Single‐Grain Scratching of Ti–6Al–4V

Advanced Engineering Materials, EarlyView.
Single‐grain scratching of Ti–6Al–4V is investigated under controlled, oxygen‐free, and ambient atmospheres using a novel experimental setup with in situ high‐speed imaging. The approach enables direct observation of chip formation and adhesion under suppressed oxidation.

CO/H2 Abundance Ratio ~ 10^{-4} in a Protoplanetary Disk

, 2014
The relative abundances of atomic and molecular species in planet-forming disks around young stars provide important constraints on photochemical disk models and provide a baseline for calculating disk masses from measurements of trace species.

Detection of Powerful Mid-IR H_2 Emission in the Bridge between the Taffy Galaxies [PDF]

, 2012
We report the detection of strong, resolved emission from warm H_2 in the Taffy galaxies and bridge. Relative to the continuum and faint polyclic aromatic hydrocarbon (PAH) emission, the H_2 emission is the strongest in the connecting bridge, approaching
