A corrosion-inhibiting mixture of compounds has been developed for addition to the water used to rinse metal parts that have been cleaned with aqueous solutions in preparation for adhesive bonding of the metals to rubber and rubberlike materials. Prior to the development of this corrosion inhibitor, the parts (made, variously, of D6AC steel and 7075-T73 aluminum) were rinsed by deionized water,...

The novel processing concept of direct quenching and partitioning (DQ&P) has been explored with a medium-carbon (0.4 wt.% C) steel to evaluate optimize the route for excellent property combinations. New compositional design approach was based on physical simulation studies aiming understand influence varying silicon contents (1.5, 0.75 0.25 wt.%) Q&P parameters microstructural development inclu...

The article presents the results of metallographic and tribotechnical studies composite coatings based on aluminum with a high copper content formed inner surface workpiece by centrifugal induction surfacing. According to study, more than 40 wt.% structure is θ-phase (Al2Cu) inclusions т-phase grains (Cu3NiAl6 ), particles silicon, tin iron-containing phases. This has hardness parameter coeffic...

the present article considers the nd:yag pulsed laser welding of 304 stainless steels with two different compositions. the effects of various laser operational parameters and cooling rates on the weld microstructures were considered. the results show that ferritic solidification is produced in the stainless steel with the creq/nieq ratio of 1.7, and austenitic solidification is produced in the ...

Southwest Research Institute (SwRI ® ) conducted a study to determine whether pulsed x-ray sources used in conjunction with amorphous silicon real-time imaging plates could provide equivalent radiographs to those obtained using isotopic sources with conventional radiographic film for inspection of schedule 40 steel pipe. Radiographic procedures for the two techniques were developed; test welds ...
