How to use Nickel alloy 400
Introduced an 1905 Monel was the pioneer of the nickel based alloys offering high strength and good corrosion resistance. Its toughness and good wear properties made it very popular with pump and valve manufacturers. Although over shadow...Views -
Application of new anti-corrosion materials and technologies in military vehicles(2)
3 Application of anti-rust products such as anti-rust oilWhen military vehicles leave the factory, it is best to perform anti-rust treatment on the body and other parts. That is, in places where there is a lot of moisture and soil...Views -
Application of new anti-corrosion materials and technologies in military vehicles(1)
Most military vehicles have complex structures. In addition to steel and alloys, there are many non-metallic materials such as rubber and plastics. There are different degrees of corrosion and aging during storage and use. In addition, t...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(6)
4.3Effects of Oxygen-Induced Grain Boundary Embrittlement on Creep Properties In powder metallurgy, it is challenging to control the oxygen content of an alloy because alloy powders easily attract oxygen from the atmosphere. In nickel su...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(5)
4.2. Heat Treatment and Anisotropy Effects on Creep PropertiesFirst, we considered the grain morphology effect on creep properties. In the as-built condition, both HX and HX-a specimens exhibited columnar grain formation (Figure 5). Colu...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(4)
Figure 12 shows the microstructures of the vertical specimens along the loading direction after the creep test. The HX as-built specimen had large cracks (Figure 12a) along the horizontal grain boundary; these cracks merged and formed si...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(3)
3.1.2.ST Specimens Figure 6 shows SEM micrographs after ST heat treatment. The boundaries of molten pools and dendritic structures disappeared. The HX ST specimen presented equiaxed grain morphology at lower magnification (Figure 6a). Th...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(2)
1.Materials and MethodsThe exact chemical compositions (in mass%) of Hastelloy-X alloys with 0 and 0.12 yttrium are called HX and HX-a, respectively, and are shown in Table 1. These two specimens were built in the shape of a 45 × 45 × ...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(1)
Abstract: We studied the effects of the rare earth element yttrium (Y) on the hot cracking and creep properties of Hastelloy-X processed by selective laser melting. We used two different alloys to study hot cracking in Hastelloy-X:...Views -
