Impact Toughness of an Isothermally Treated Zeron®100 SDSS [PDF]

Journal of Materials Engineering and Performance, 2012
The aim of the present study is to investigate the impact toughness of a UNS 32760 SDSS, in relation to the quantity of secondary phases precipitated after isothermal aging in the range of 850-950 °C and for different exposure times. The impact toughness has been investigated by means of instrumented impact testing, using Charpy V-notched specimens at ...

Nitride‐Reinforced Metal Matrix Nanocomposite Powders Production by Plasma‐Assisted Thermochemical Treatment of Intermetallic Powders

Advanced Engineering Materials, EarlyView.
This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.
