The objective of this study is to explore and compare the mechanical response AlCrSiN coatings deposited on two different substrates, namely, WC-Co cBN. Nano-indentation was used measure hardness elastic modulus coatings, micro-indentation for observing contact damage under Hertzian with monotonic cyclic (fatigue) loads. Microscratch tests were also evaluate strength adhesion between substrates...

A Ti40Zr40Ni20 quasicrystal (QCs) rod and ribbons were prepared by conventional casting rapid solidification. The X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission (TEM) differential calorimeter (DSC) techniques used to investigate the microtissue, phase composition, solidification features of samples; nano-indentation test was carried out at room temperature. results...

Fe-based amorphous alloys often exhibit severe brittleness induced by annealing treatment, which increases the difficulties in handling and application industry. In this work, shear transformation zone its correlation with fracture characteristics for FeSiB alloy ribbons different structural states were investigated. The results show that bending strain decreases sharply temperature increase, a...

asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. this is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. this paper presents the evaluation of fatigue behaviour of nano reinforced stone mastic asphalt mixtures. fatigue...

Indentation creep tests were performed on an Al-5.3mol% Mg solid-solution alloy to examine whether mechanical properties can be extracted accurately from a testpiece, as small as a rice grain. A conical diamond indenter was pressed into a test surface with a constant load F at temperatures ranging from 0.60 to 0.65 Tm (Tm: the absolute liquidus temperature). When the representative flow stress ...

Theoretical analysis and finite element (FE) simulation have been carried out for a constant specific load rate (CSLR) indentation creep test. Analytical results indicate that both the representative stress and the indentation strain rate become constant after a transient period. Moreover, the FE simulation reveals that both the contours of equivalent stress and equivalent plastic strain rate u...

The application of incremental processes in the manufacturing industry is having a great development in recent years. The first stage of an Incremental Forming Process can be defined as an indentation. Because of this, the indentation process is starting to be widely studied, not only as a hardening test but also as a forming process. Thus, in this work, an analysis of the indentation process u...
