Special Issue Information

Dear Colleagues,

A wide range of activity sectors, from systems for water supply to the aeronautics and space industries, currently used composites.

Composite pipes have many potential advantages over conventional pipes. The excellent mechanical properties, low specific weight, high specific stiffness, good thermal insulation and corrosion resistance form the basis of the increasing volume of applications.

Piping testing involves checking for tightness, durability, mechanical strength to pressure and other external stresses, as well as analysis of adhesion between the layers of the tube. On the other hand, the numerical simulation of pipe strength requires the properties of the constituent materials as well as the characteristics of the bond between the layers of the composite formed by the metal / plastic or metal / ceramic or other pairs.

This Special Issue presents: (i) Types of raw materials, including property enhancement additives such as nanomaterials for composite metal pipes manufacturing; (ii) Technologies for composite metal pipes manufacturing; (iii) Properties of composite metal pipes, including numerical modeling and simulation; and (iv) Applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
The microstructure and corrosion resistance in H2S environments for various zones of X80 pipeline steel submerged arc welded joints were studied. The main microstructures in the base metal (BM), welded metal (WM), coarse-grained heat-affected zone (CGHAZ), and fine-grained heat-affected zone (FGHAZ) [...] Read more.
The microstructure and corrosion resistance in H2S environments for various zones of X80 pipeline steel submerged arc welded joints were studied. The main microstructures in the base metal (BM), welded metal (WM), coarse-grained heat-affected zone (CGHAZ), and fine-grained heat-affected zone (FGHAZ) were mainly polygonal ferrite and granular bainite; acicular ferrite with fine grains; granular bainite, ferrite, and martensite/austenite constituents, respectively. The corrosion behavior differences resulted from the microstructure gradients. The results of the micro-morphologies of the corrosion product films and the electrochemical corrosion characteristics in H2S environments, including open circuit potential and electrochemical impedance spectroscopy, showed that the order of corrosion resistance was FGHAZ > BM > WM > CGHAZ.
