Characterization of new membrane materials by means of fouling experiments Adsorption of bsa on polyetherimide-polyvinylpyrrolidone membranes [PDF]

, 1991
The hydrophilicity of polyetherimide-polyvinylpyrrolidone (PEI-PVP) microfiltration membranes can be adjusted by means of a suitable post-treatment. The influence of the nature of the membrane surface on fouling properties was studied using permeation ...

Post weld heat treatment effects on SMSS deposit mechanical properties [PDF]

, 2015
Supermartensitic stainless steels have been developed as an alternative technology, mainly for oil and gas industries. In these steels, the post-weld heat treatments are usually double tempering treatments, to ensure the complete tempering of martensite ...

Fatigue analysis of thin AlMgSi welded joints under constant and variable amplitude block loadings [PDF]

, 2003
This paper reports the fatigue behaviour of thin AlMgSi1 aluminium alloy weldments and the improvement in fatigue strength due to post-weld treatments. Several fatigue tests were performed using two distinct types of thin welded joints, T and single lap,

Mechanical property strengthening by post-heat treatments in NiTiCu shape memory alloys fabricated by twin-wire arc additive manufacturing

Virtual and Physical Prototyping
To address the challenges of wide transformation hysteresis as well as the poor properties of NiTi-based alloys fabricated by twin-wire arc additive manufacturing, post-heat treatments were employed in as-deposited NiTiCu alloys.

Influence of post weld heat treatment for weld joint of P355GH

MATEC Web of Conferences, 2018
From steel designed to work under pressure and exposed to high temperature apart from the good weldability, good mechanical properties are required. The guidelines set by the regulations require post welding heat treatment above 35mm thick.

Structural and electrical properties of CuAlMo thin films prepared by magnetron sputtering [PDF]

, 2013
The structural and electrical properties of a low resistivity CuAlMo thin film resistor material were investigated. The thin films were grown on Al2O3 and glass substrates by direct current (dc) magnetron sputtering.

Mechanical, structural and dissolution properties of heat treated thin-film phosphate based glasses [PDF]

, 2017
Here we show the deposition of 2.7 μm thick phosphate based glass films produced by magnetron sputtering, followed by post heat treatments at 500 °C. Variations in degradation properties pre and post heat treatment were attributed to the formation of ...
