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...
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...
Abstract Nanohardness and Effective Elastic Moduli were measured for pulsed-Gas Tungsten Arc Welded Ti-5Al-2.5Sn alloy using autogenous mode through nanoindentation atomic force microscopy. Experiments conducted a Berkovich tip on nanoindentor with elliptical pile ups an Atomic Force Microscope. effective elastic moduli calculated in the base metal, heat affected zone fusion of weldments differ...
Abstract In chemical mechanical polishing (CMP) for IC fabrication, porous pads are critical achieving extremely consistent throughput in CMP process. The pad hardness, porosity of pad, and pore sizes the thermoplastic polyurethanes foam fabrication procedure determine properties pads. This paper aims to develop a methodology modeling macro micro hardness. IC1000 has been analyzed with develope...
Osteoporosis is a major age-related bone disease characterized by low bone mineral density and a high risk of fractures. Bisphosphonates are considered as effective agents treating osteoporosis. However, long-term use of bisphosphonates is associated with some serious side effects, which limits the widespread clinical use of bisphosphonates. Here, we demonstrate a novel type of bone-targeting a...
Ternary clay-based composite material (TCC), composed of lime, clay and sand, and usually modified with sticky rice and other organic compounds as additives, was widely used historically in Chinese construction and buildings due to its high mechanical performance. In this study, to gain an insight into the micromechanical mechanism of this cementitious material, the nanomechanical properties an...
