Enhancement of the thermal shock resistance of MgO–C slide plate materials with the addition of nano-ZrO2 modified magnesia aggregates

, 2020
The thermal shock resistance (TSR) of sintered magnesia aggregates which were modified by vacuum impregnation with a nano-ZrO2-alcohol suspension, and the influence of the modified aggregates on the thermal shock performance of MgO–C slide plate ...

Effects of SiC content on thermal shock behavior and elastic modulus of cordierite–mullite composites

, 2020
Cordierite (Mg2Al4Si5O18) is a commercially available ceramic with low fracture toughness that hampers its broad industrial applications. Although several studies have reported the mechanical improvement of cordierite using various reinforcements ...

Real-time detection of damage evolution and fracture of EB-PVD thermal barrier coatings under thermal shock: An acoustic emission combined with digital image correlation method

, 2020
Thermal shock failure is the most common type occurring in service. The thermal shock life is overestimated and the failure process of thermal barrier coatings (TBCs) is still not clear due to lack of environmental simulator and the real-time detection ...

Preparation and thermal shock behavior of nanoscale MgAl2O4 spinel-toughened MgO-based refractory aggregates

Ceramics International, 2019
Nanoscale MgAl2O4 (MA) spinel-toughened MgO-based refractory aggregates were prepared by firing lightly calcined magnesia powder and some nanoscale Al2O3 (≤50 nm) particles at high temperature.

Research on thermal shock resistance of porous refractory material by strain-life fatigue approach

, 2020
The study aims to investigate the effects of pore structure on the thermal shock resistance of porous refractory materials. Porous material is constituted by a solid frame and the pores filling with air. A direct thermo-mechanical coupling simulation and

Thermal-shock resistant refractories and ceramics under thermal-shock conditions

Refractories, 1988
We propose an approach to evaluating the thermal-shock resistance of solid bodies in a thermal-shock schedule based on the development of elastic waves of compression (expansion) and the final value of the velocity of the thermal waves. A model is put forward and also a calculation equation for the destructive drop in temperature ΔTp in the thermal ...

The roles of stress in the thermal shock failure of YSZ TBCs before and after laser remelting

, 2020
In order to reveal the roles of stress in the thermal shock failure of thermal barrier coatings (TBCs), yttria-stabilised zirconia (YSZ) TBCs were prepared via atmospheric plasma spraying and then remelted by a laser remelting process.
