Characterization of mechanical properties of porcelain tile using ultrasonics
(2012)
Ultrasound affords a very useful and versatile non-destructive method, using a large application area, for evaluating the microstructure and mechanical properties of materials. In this study, porcelain tiles were sintered ...
A comparative study of SiAlON ceramics
(Elsevier Sci LTD, 2012)
Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% beta-Si3N4 was used from refractory grade powders (B1) and another purer 98% alpha-Si3N4 (50A) powder was used to prepare the SiAlON ...
Wear behaviour of alpha- and alpha/beta-SiAlON ceramics stabilized with Nd2O3 and Y2O3
(Elsevier Sci LTD, 2009)
alpha- and alpha/beta-SiAlON compositions, doped with Y2O3 or Nd2O3, were densified by gas pressure sintering (GPS). The wear and mechanical properties of the materials were investigated and compared to beta-Si3N4 materials. ...
Evaluating vibration assisted vacuum infusion processing of hexagonal boron nitride sheet modified carbon fabric/epoxy composites in terms of interlaminar shear strength and void content
(Elsevier Sci LTD, 2016)
The results of an investigation of the effect of voids on the interlaminar shear strength (ILSS) of carbon fabric/epoxy composites consolidated from fabric preforms containing hexagonal boron nitride sheets (h-BNSs) were ...
Mechanical properties and thermal shock behaviour of alumina-mullite-zirconia and alumina-mullite refractory materials by slip casting
(Elsevier Sci LTD, 2003)
Strength and modulus values of slip-cast alumina-mullite-zirconia and alumina-mullite refractories have been determined as a function of quench temperature by air and water quenching. The resistance to fracture initiation ...
The effect of SnO2 on the improvement of mechanical properties of MgO-MgAl2O4 composites
(Elsevier Sci LTD, 2012)
Incorporation of SnO2 into MgO-spinel (M-S) increased mechanical properties significantly. Relationships between the parameters improving mechanical properties and microstructural variables were examined. Basic parameters ...
The usage of newly developed glass fibre in cement structure and their characterization
(Elsevier Sci LTD, 2018)
In this work, recently developed Zrnl glass fibres belonging to the SrO-Mn2O3-Fe2O3-MgO-ZrO2-SiO2 (SMFMZS) system have been used as reinforcing materials in cement. The highest (2.610 N/mm(2)) compressive strength value ...
Improvements on the mechanical properties and thermal shock behaviours of MgO-spinel composite refractories by ZrO2 incorporation
(Elsevier Sci LTD, 2012)
Microstructural features and improvements on the mechanical properties and thermal shock behaviours of MgO-spinel composite refractories with ZrO2 addition were examined. ZrO2 incorporation into MgO-spinel led to improvements ...
A comparison of sintering techniques using different particle sized beta-SiAlON powders
(Elsevier Sci LTD, 2012)
In the present study sintering behavior and mechanical properties of beta-SiAlON ceramics were investigated using different sintering techniques (gas pressured sintering (GPS), pressureless sintering and spark plasma ...
Developments on the mechanical properties of MgO-MgAl2O4 composite refractories by ZrSiO4-3 mol% Y2O3 addition
(Elsevier Sci LTD, 2012)
Improvements and the effects of additions of ZrSiO4-3 mol% Y2O3 into MgO-MgAl2O4 composite refractories on mechanical properties and thermal stress resistance parameters were investigated. Significant improvements were ...
