Special Issue Information

Dear Colleagues,

Soldering and brazing go a long ways back and are constantly improving. Due to the continuous progress in science and technology, a variety of soldering/brazing methods are being derived gradually. The choice of solder alloy greatly affects the strength of a soldered/brazed joint. Firstly, the strength of the solder itself can directly determine the strength of a soldered/brazed joint. Secondly, the composition of the solder alloy can determine the metallurgical reaction between the solder and the base metal, thus affecting joint performance. Thirdly, the choice of solder alloy can affect the heating temperature, welding environment, etc., thereby affecting the softening and corrosion resistance of the joint.

With the view of analyzing soldering and brazing technologies, we offer this Special Issue entitled "Reliability Evaluation of Solder Alloys in Practical Applications". The purpose of this Special Issue is to organize information about the relationships between solder alloys and joint strength. We invite you to contribute research that studies the effect of solder alloys on microstructure evolution and the mechanical properties of soldered/brazed joints.

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.

The welded joint of a dissimilar titanium alloy was obtained via inertial friction welding technology. The characteristics of the bonding interface and the microstructure of the welded joint were investigated via optical microscopy, scanning electron microscopy and electron backscattered diffraction. The results show that fine, equiaxed grains and interdiffusion bands of the elements Mo and Sn were formed in the weld zone under the high temperature and plastic deformation of the inertial friction welding. The weld zone and thermo-mechanically affected zone formed 1¯21¯0 α texture and 111 β texture, respectively. Full article
