The obtained results showed that the coating at the spray current of 300 A, the air pressure of 5.5 bar and the stand-off distance of 162.8 mm has the lowest porosity and highest microhardness. In addition, this coating also has better adhesion to the steel substrate and wear resistance than other coatings. Moreover, X–ray phase analysis showed that the following phases are created on the surface of the Al-Mg coatings: Al, Al2MgO4 and Al3Mg2.

"Standard Specification for High-Strength Low-Alloy Structural Steel" covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction intended primarily for use as structural members where savings in weight [mass] or added durability are important. The atmospheric corrosion resistance of the steel in most environments is substantially better than that of carbon structural steels with or without copper addition. When properly exposed to the atmosphere, this steel can be used bare (unpainted) for many applications.

This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition (see Note 1). When properly exposed to the atmosphere, this steel is suitable for many applications in the bare (unpainted) condition.

Manganese steels have been widely used in industries due to their good wear resistance, high work hardening ability, and high toughness and ductility. This research investigated the effect of modification, i.e., FeTi and Mischmetal, on the grain size and mechanical properties of the high manganese steel (13–15 wt.%).

This research investigates a means of negating such shortcomings and reaping the benefits of both LPBF additive manufacturing and traditional manufacturing methods by joining such parts together using laser welding in the autogenous mode (no fillers required). Based on the literature review conducted in this field and the gaps identified, a two-stage methodology was utilised, as per following.

Laboratory-scale experiments were carried out to improve the strength of prestressed steel by combination of the Cr-Ti alloying and heat treatment. A predetermined amount of the scrap and some ferrous alloys (such as FeMn, FeSi, FeCr and FeTi) was melted in the induction furnace to obtain the aimed compositions of the steel ASTM A633 grade C and the modified steel with Cr-Ti alloying.
