Investigating the influence mechanisms of cryogenic treatment on mechanical properties and wear resistance of AISI 4340 steel

Journal of Materials Research and Technology
This study systematically investigates the multiscale structural evolution of cryogenic treatment processed AISI 4340 steels. It revealed that cryogenic treatment refined martensitic block structures and increased high angle grain boundaries, while ...

Mapping erosion-corrosion of carbon steel in oil-water solutions : Effect of velocity and applied potential

, 2012
In this study, the combined effects of erosion and corrosion on carbon steel were investigated in three environments containing crude oil, reservoir water, and a mixture of both solutions at a range of applied potentials, velocities and impact angle. The

Cladding of stainless steel on carbon steel

Le Journal de Physique IV, 1999
The possibility of producing anticorrosion and wear resistant cladding from stainless steel onto tool and carbon steels by means of melting in high energy density light flux is demonstrated. Experiments are conducted in an installation with two arc xenon lamps of 10 kW power of each.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Inhibition of pitting on carbon steel [PDF]

, 2011
Carbon dioxide and hydrogen sulphide pitting related failures are a prime concern in oil and gas internal pipelines. Often, these types of failure have a great impact on safety and environmental matters and can cause severe financial consequences to the

Achieving exceptional strength-low temperature toughness synergy in the microalloyed medium carbon steel via layered heterogeneous structure

Materials & Design
The further advancement of microalloyed medium carbon steels is often limited by low-temperature toughness instability. A microalloyed medium carbon steel with both strength and low-temperature toughness was produced through a warm rolling and short-time

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
