The use of multi-materials structures is nowadays one of the most sought solutions to
decrease weight and reduce both emission of greenhouse gases and fuel consumption in …

The industrially-important WC-Co composite materials provide a useful, albeit complicated
materials system for understanding the combined influences on hardness and strength …

Highlights•We used indentation testing and microscopy to characterize ZTA and
SiC.•Moduli, hardness, toughness were measured at low, intermediate and high loads …

This work investigates the feasibility to the fabrication of high density of fine alumina–5wt.%
zirconia ceramics by two-step sintering process. First step is carried out by constant-heating …

Surprisingly, certain α-phase alumina filler particles at one to five weight percent can reduce
the wear rate of polytetrafluoroethylene (PTFE) by 10,000 times, while other, seemingly …

Abstract Alumina (α-Al 2 O 3), one of the most widely used structural ceramics for industrial
applications, requires high temperature and long sintering time to achieve a fully dense …

It is demonstrated that 0.1 wt% of multi-walled carbon nanotubes (MWCNTs) or single-
walled carbon nanotubes (SWCNTs) added to zirconia toughened alumina (ZTA) …

Brittleness is a major limitation of polymer-derived ceramics (PDCs). Different concentrations
of three nanofillers (carbon nanotubes, Si3N4 and Al2O3 nanoparticles) were evaluated to …

A two-dimensional finite element model is developed to investigate intergranular fracture in
alumina under compression. The grain interiors are modeled as anisotropic elastic and the …

A two-dimensional finite-element model is developed to investigate transgranular fracture in
polycrystalline alumina under tensile loading. Microcracking is modeled explicitly using the …
