The experimental results indicate that a carbon-tunsten alloy cladding on a poor quality steel surface greatly improves its mechanical properties, the cladding thickness are inversely propotional to the square of laser scanning speeds.
In this review article, the development of the double cladding optical fiber for high power fiber lasers is reviewed.

Failure analysis of the hermetical AISI 304L stainless steel cladding in oxidative chlorination reactor shows that its pitting and stress corrosion arose due to the presence of chlorine ion in the working environment.
The possibility of the development of Fe-Mn-Al austenitic steels has been investigated with special attention paid to the effect of Mo, W, Ti, V, Cr or Si on the stability of austenite, their high-temperature strength and tonghness, as well as their resistance to oxidation and corrosion.It was found that two alloys have good tensile and stress-rupture properties comparable to those of high Cr-Ni bearing steels such as 257 Ti and one alloy has oxidation resisting property similar to that of 13% Cr steel. How...
Duralumin 2024 has been extruded under different conditions. Results of mechanical testing show that when billets have not been homogenized and have been extruded at 475℃ or when they have been homogenized and have been extruded at 450℃, the strength of the extruded products is 10% more higher than that of billets extruded at 360°-420℃. 2. The flow pattern of residual parts of duralumin billets, directly extruded at different temperatures, with or without, lubricants and with aluminum cladding or inve...
This paper was aimed at investigatiing the influence of post-weld heat treatmenton the mechanical properties of stainless steel overlaid joint and discussing the relaiionbetween the change in impact toughness and micro structure in the overlaid cladding.The base metal was Q-T treated Ni Cr-Mo-V high strength steel.In the inner surfaceof vessel two layers of clad metal were deposited by submerged arc weldingwith chromium-nickel stainless steel strip as the consumable electrode.The first layerwas 0Cr20N...
