MICROSTRUCTURES OF LASER CLAD ZONE FOR Fe-,Ni-,AND Co-BASE ALLOY COATINGS激光表面熔覆Fe 基、Ni基和Co基合金涂层的显微结构Laser cladding technique has been applied to renovate some partially-damaged (or worn) components with Fe, Ni, Co-base alloys, hence to improve their hardness values and ...
The ductility of a single-phase Ni20% Cr alloy and two precipitation-hardened Ni20% Cr-base alloys, hardened by Ni3(Al, Ti) and Ni3(Al,Nb), respectively, has been studied over a range of temperature at various strain rates. The results show that the alloy hardened by Ni3(Al,Nb),...

Compared to Nb, Mo has a relatively higher solubility in Ni–Co alloys and can suppress the formation of detrimental intermetallic phases [29]. Indeed, Liu et al. [30] and Liang et al. [21] reported that Mo increased the γ' solvus temperature of Co–Ni-based superalloys. Therefore, Mo...
A new kind of Ni–Co-base superalloys with a γ/ γ′ two-phase structure has been proposed recently for turbine disk applications. Some of these Ni–Co-base superalloys are assessed by tensile tests. The results show that the Ni–Co-base alloys can be processed by cheap cast and wrought...
另一方面,Co容易活化成Co60,它是一种穿透力很强的高毒性核辐射元素,半衰期长达5.27年。从20世纪80年代起,技术人员已经开始研制用于高温耐磨堆焊领域的代钴材料 [1-4] 。如哈尔滨焊接研究院研制的以C、Cr、W、Si等元素强化的NDG-2#镍基合金,曾用于上海阀门厂微启式安全阀阀座堆焊;苏州大学刘双 [5] 等进行...
