Improvement in Slag Resistance of No-Cement Refractory Castables by Matrix Design

Ceramics, 2020
The corrosion resistance of spinel containing cement bonded castables has been extensively investigated in the past. However, corrosion of no-cement refractory castables (NCC) has not been widely studied since the use of NCC has been relatively limited ...

Thermophysical Properties of the Desulphurization Slags With Various CaS and CaO/Al2O3 Ratio

Advanced Engineering Materials, EarlyView.
This article investigates how CaS content and the CaO/Al2O3 ratio influence the thermophysical properties of desulphurization slags. Using experimental measurements and thermodynamic simulations, this study reveals complex effects on viscosity, surface tension, and density, providing new insight into slag structure and phase behavior under ...

Fiber reinforced refractory castables for SPF toolings [PDF]

Materialwissenschaft und Werkstofftechnik, 2008
AbstractFiber reinforced refractory castable (FRRC) is an emerging material solution to manufacture SPF tools for forming titanium alloy sheets. Indeed, FRRC are able to conserve good mechanical properties up to 900 °C. Fiber reinforcement allows to improve mechanical properties and to avoid a catastrophic failure.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Study of the dimensions of double-torsion test specimens

Materials Research, 2008
Double-torsion tests were carried out to ascertain whether a thin test specimen would affect the results of this test. The tests involved two test specimen sizes, one with a thickness five-fold greater than the particle size of the material and the other

Sizing of Refractory Castable Gas-Burner Using Thermomechanical Simulations [PDF]

Advances in Science and Technology, 2010
Damage is a crucial characteristic of refractory castables and has to be considered to simulate correctly the behaviour of refractory structures. But, damage modelling by finite element simulations remains difficult. Indeed, the use of a continuum damage model with softening leads to strain localization phenomena.
