摘要: The addition of refractory elements is effective in improving the comprehensive performance Ni-based superalloys, and meanwhile, precipitation trend TCP phases increases with content due to segregation during high temperature service. obviously decreased creep properties rupture life superalloys. toughness plastic superalloys also dramatically deteriorated. Ruthenium (Ru) shown suppress formation resulting much improved resistance microstructural stability. studies on including crystallography effect alloy composition are reviewed.
