Evaluation of thinning behaviour under the influence of plastic hardening and surface friction during small punch test

open access: yesFracture and Structural Integrity
Understanding the deformation response of the material involving thinning under small punch loading is vital to ensure structural integrity. This paper systematically investigates the effects of plastic hardening on the thinning process under different ...

Surface Modification of a Nickel-Free Austenitic Stainless Steel by Low-Temperature Nitriding

open access: yesMetals, 2021
Low-temperature nitriding allows to improve surface hardening of austenitic stainless steels, maintaining or even increasing their corrosion resistance. The treatment conditions to be used in order to avoid the precipitation of large amounts of nitrides ...

ULTRASONIC EFFECT ON ELECTRIC SPARK FORMING AND DEVELOPMENT IN ELECTROACOUSTIC SPRAYING

open access: yesAdvanced Engineering Research, 2018
Introduction. The electroacoustic application of wear-resistance coatings is studied. The work objective is to obtain a mathematical model of the ultrasonic effect on the formation and development of an electric spark occurring in the process of the ...

Clinkerless slag-silica binder: hydration process and hardening kinetics (part 2)

open access: yesИнженерно-строительный журнал, 2020
In part 1 of the studies, it was shown the results of the implementation of the “top–down” nanotechnological principle to obtain clinkerless binder with a high content of microsilica, activated during grinding what allowed to increase their hydraulic ...

Cold hardening and dehardening in Salix [PDF]

open access: yes, 2003
The variation in cold hardiness in Salix in the autumn was investigated using clones of different geographic origins. In late growing season, the variation was small and inversely related to a phenotypic variation in potential growth rate.

'Fire hardening' spear wood does slightly harden it, but makes it much weaker and more brittle [PDF]

open access: yes, 2016
It is usually assumed that 'fire hardening' the tips of spears, as practised by hunter-gatherers and early Homo spp., makes them harder and better suited for hunting.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Numerical modeling of strain rate hardening effects on viscoplastic behavior of metallic materials [PDF]

open access: yes, 2017
The main goal of the present work is to provide a finite strain elasticviscoplastic framework to numerically account for strain, strain rate hardening, and viscous effects in cold deformation of metallic materials. The aim is to provide a simple and robust

Deforming glassy polystyrene: Influence of pressure, thermal history, and deformation mode on yielding and hardening [PDF]

open access: yes, 2009
The toughness of a polymer glass is determined by the interplay of yielding, strain softening, and strain hardening. Molecular-dynamics simulations of a typical polymer glass, atactic polystyrene, under the influence of active deformation have been ...
