Environmentally assisted cracking in the low pressure superheated hydrogen steam

نویسندگان

چکیده

Abstract Low pressure superheated H 2 -steam appears to be an interesting alternative pressurized water environments, since it is capable of performing accelerated environmentally assisted cracking (EAC) experiments for nickel base and stainless steel alloys. Constant Extension Rate Tensile (CERT) tests were performed with displacement rates 2×10 -6 or -8 ms -1 at 350, 400, 440 480 °C on flat tapered specimens Type 316L austenitic steel. The shape allows the determination crack initiation over a range stresses strains simultaneously one specimen therefore threshold stress value was obtained. environment 6 times more oxidizing than dissociation NiO. acquired mechanical properties are summarized EAC evaluated.

Using Superheated Steam in Drying and Sterilization

Botanicals are received in whole, non-sterile form. BI Nutraceuticals sterilizes, mills, and packages the ingredient in sturdy, safe containers before shipping to customers. Photo courtesy of BI Nutraceuticals Using Superheated Steam in Drying and Sterilization It seems counterintuitive to use water vapor in a process to remove water or to heat materials that can be damaged by moisture, but suc...

Modelling the Drying of Porous Coal Particles in Superheated Steam

The modelling and simulation of drying porous coal particles in superheated steam was investigated in this paper. Improved transport and kinetic parameters as well as particle shrinkage were considered in arriving at the results. The resulting partial differential equation describing the drying process was solved numerically using the finite element analysis in addition to other useful equation...

Effect of colloidal Particles associated with the liquid bridge in sticking during drying in Superheated Steam

It is very important in the design of a drying system is to evaluate sticking behaviour of the materials goes under drying. A new approach to the sticking issue is applied in this study by carrying out a sticking test for the liquid associated with the materials under study. It was found that the liquid bridge is responsible of the initial sticking of the materials to the contact surface and th...
