Orientation Dependence of Stress Rupture Properties of a Ni-based Single Crystal Superalloy at 760℃Shaohua Zhang,Dong Wang,Jian Zhang and Langhong Lou Superalloys Division,Shenyang National... in these specimens.The rupture properties and the deformation mechanisms were discussed based on the dislocation pattern and the calculated Schmid factors for different specimens.关键词:......
or revert proportion in reverted alloys. Increasing N content considerably reduces the mechanical properties of both cast Ni-based superalloys and Co-based superalloys. In cast Ni-based superalloys... content results in a greater degree of microporosity, which leads to a significant decrease in the mechanical properties of cast Ni-based superalloys. In Co-based superalloy, high N content will extend......
