“…The ratio of γ/α 2 is estimated by 61,264/38236 ≈ 1.6 according to the main peak areas of the two phases. However, γ phase was not detected in the 15-45 μm and 45-106 μm powders because of the faster cooling rate for fine powders [39,40].…”

In this study, the characteristics and solidification behavior of Ti-48Al-3Nb-1.5Ta powder produced by supreme-speed plasma rotating electrode process (SS-PREP®) were investigated. The microstructure, phase and characteristics were analyzed by scanning electron microscopy, X-ray diffraction and other methods. The atomization mechanism is direct drop formation. The relationship between the particle size and cooling rate is, and the relationship between secondary dendrite arm space and the particle size is = 0.028d + 0.11 , as well as the relationship between SDAS and cooling rate is = 4.84 × 10 5 ⋅ T −1.43 . With increase in particle size, the surface structure gradually changes from the featureless smooth structure to dendritic and cellular dendritic morphology, and the flow ability becomes better. The carbides mainly exist within 5 nm of the surface and the oxidation layer is about 20 nm thick. Ti-48Al-3Nb-1.5Ta powder was mainly composed of α 2 phase and γ phase. With increase in particle size, the content of γ phase increases, and the hardness decreases accordingly. The 106-250 μm particles are composed of multiple grains with the grain size of 70-80 μm. The microstructure, phase composition and hardness of different TiAl powders with the same size are similar, but the elastic modulus is different.

“…The process of vacuum electron beam welding and rolling is widely used due to its high production efficiency, low environmental pollution and flexible product specifications. In the production of single-sided stainless steel clad plates, in order to control the shape of the plate, welded symmetrical compound slabs are generally applied and the single-sided stainless steel clad plate is obtained by cutting after rolling [5][6] . However, symmetric rolling not only increases the steps of slab preparation and cost, but also reduces the production efficiency.…”

The hot rolled single sided stainless steel clad plate of 316L stainless steel and Q345C steel was carried out in a hot rolling line by the technology of “electron beam vacuum welding and hot rolling”. High quality single sided stainless steel clad plates were produced by asymmetrical compound billet and asymmetrically rolling. The productions of stainless steel clad plate have reached the requirements of GB / T 8165-2008. The interface shear strength is greater than 320 MPa. The yield strength is greater than370 MPa. The tensile strength is greater than 520 MPa. The elongation is greater than 30%, A good metallurgical bonding between stainless steel and carbon steel was achieved. The bonding rate reached 100%. The composite interface is straight and perfect. The pilot production in the study has laid down the certain basis for the production of the single-side dissimilar-material composite board.

“…Presently, domestic and foreign scholars have carried out a lot of research on the erosion wear of steel structure coatings [6][7][8][9][10][11] . Liu M W et al [6] focused on the erosion damage law of steel member coatings under sand-laden water flow. They found that the coating thickness loss increases with the increase of punching angle and then decreases, and the erosion damage of the coating was most serious when the punching angle was about 40°.…”

A three-dimensional numerical model is established by reference to the erosion test of wind-blown sand. The erosion wears characteristics of the galvanized coating under different sand erosion conditions was studied using existing experimental data and the Oka erosion model. The research results indicate that the maximum erosion rate of galvanized coating increases at first and then decreases when the sand attack angle increase, and reaches the maximum value when the sand attack angle is 30°, reaches the maximum value when the sand attack angle is 30°; the erosion rate of galvanized coating increases exponentially with the increase of wind-blown sand velocity, and there are two erosion stages: high speed and low speed. The erosion rate of galvanized coating increases when sand flux increases. The erosion rate increases linearly with the increase of sand flux at a low attack angle but at a high attack angle, and then the growth rate becomes slower. The study’s results support the protection of steel structures and the evaluation of the durability of galvanized coatings.
