Mechanical characterization of dielectric ceramics, which have drawn extensive attention in
wireless communication, remains challenging. The micromechanical properties with the …

Three kinds of Dy 3+ ion-doped (Lu x Y 1-x) 3 Al 5 O 12 (x= 0, 1/3, 1/2) single crystals
fabricated by the Czochralski method with 4 at.% Dy 3+ ion doping were investigated by …

Multiphase boride layers consisting of (CoFe) 2 B,(Fe 0.4 Mn 0.6) B, Cr 2 Ni 3 B 6 and (Cr
0.4 Mn 0.6) B were formed on the surface of Co 1.21 Cr 1.82 Fe 1.44 Mn 1.32 Ni 1.12 Al 0.08 …

Tensile properties can be evaluated by defining representative stress and strain with the
parameters obtained from instrumented indentation tests using a spherical indenter. The …

A new instrumented spherical indentation test (ISIT) methodology is proposed to determine
fracture toughness of metallic materials that their strain hardening can be adequately …

There has been a huge expansion in the laying of pipelines for the transmission of fossil
fuels over large distances and in dire environments. Large diameter pipes can be …

Berkovich nanoindentation experiments were conducted on Zr 55 Cu 30 Al 10 Ni 5 bulk
metallic glass under a constant loading rate. Indentation hardness decreased linearly with …

The fatigue resistance of metallic materials is generally attributed to both strength and
toughness. Unfortunately, these properties are mutually exclusive in most materials …

In the present work, the fracture toughness and tensile property of 40CrNiMoA high-strength
steel were systematically investigated. The experimental results reveal that the ultimate …

Micromechanical modelling of void nucleation in ductile metals indicates that strain required
for damage initiation reduces exponentially with increasing stress triaxiality. This feature has …
