The respective NW shapes observed after 20 min elapse show very differing behavior; liquid-like melting (phase-1), partial melting (phase-2), and solid-like hardness (phase-3).
The nanoindentation hardness and phase transformation temperature of the high-alloy martensite were measured.
The coatings were examined by means of optical microscopy, X-rays diffraction and Vickers microhardness in terms of the coating's morphology, thickness, hardness and phase formation.
The effect of laser remelting process on the surface roughness, microstructure, grain size, hardness and phase transformation was investigated.
It was determined that the average indentation modulus and hardness of phase 5 were 32.5 ± 4.2 GPa and 1.03 ± 0.19 GPa, respectively.
A three-dimensional thermal model is used to predict the workpiece temperature distribution, which is coupled to a two-dimensional kinetic model to predict the resultant hardness and phase distribution.
In this work we studied the influence of the nitriding atmosphere composition on hardness, microstructure, phase composition and wear resistance of duplex treated cold work PM tool steel alloyed with niobium (2.6 wt.%).
The rigidity of the abrasive film reduces the impact of the variation in hardness of phases within the sample.
Usually, nanoindentation is used to study the mechanical properties of materials in nanometer scale, such as nano-hardness and phase transformation under stress [8, 22, 24]. Figure 13 shows the stress directions on the cross section in nanoindentation with a spherical indenter.
The surface properties such as microstructure, crystalline phase, hardness, and porosity of WC CrC Ni coating have been investigated.
The film hardness, corrosion behavior, phase composition, and texture were determined.
