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. ...
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 mullite on the mechanical properties and thermal shock behaviour of alumina-mullite refractory materials
(Elsevier Sci LTD, 2003)
Mechanical properties and thermal shock behaviour of slip-cast alumina-mullite refractories have been investigated. There was a marked improvement in strength, Young's modulus and fracture toughness values with the addition ...
The effects of processing on the alpha <-> beta SiAlON transformation during cycling heat treatments
(Elsevier Science Sa, 2008)
Typical alpha/beta-SiAlON starting composition of formula Nd(0.33)Si(9.38)Al(2.62)O(1.62)N(14.38) was densified by two different sintering processes, hot pressing (HP) and gas pressure sintering (GPS), using Nd(2)O(3) as ...
Effect of the particle size distribution of spinel on the mechanical properties and thermal shock performance of MgO-spinel composites
(Elsevier Sci LTD, 2003)
The influence of varying the amounts of spinel with a similar median particle size, but with different distribution, on the mechanical properties and thermal shock performance of MgO-spinel composites was investigated. ...
The influence of different CaO source in the production of anorthite ceramics
(Elsevier Sci LTD, 2009)
The effects of starting raw materials and firing conditions oil anorthite (CaAl2Si2O8) phase formation are investigated by differential thermal analysis (DTA)-thermogravimetry (TG) and X-ray powder diffraction (XRD). Four ...
Processing and characterisation of three-layer alumina-based composites with enhanced damage tolerance
(Elsevier Sci LTD, 2005)
Three-layer alumina-based composites reinforced with iron in the inner layer and with chromium in the outer layers were fabricated by first uniaxially pressing the three-layer assembly, followed by cold isostatic pressing ...
