研究了含氧活性添加剂的镍基和铁基合金在1200/sup 0/C空气中氧化诱导的类栓形貌的生长。根据形态学和生长机制确定了两种类型的钉。它们的发展可以用经典的内氧化理论或短路扩散模型来解释。基于微压痕下鳞片的断裂行为，讨论了合金/鳞片韧性的提高。八位数。
The oxidation-induced growth of a peg-like morphology in Ni and Fe based alloys, containing oxygen-active additions, was investigated at 1200/sup 0/C in air. Two types of pegs were identified based on morphology and growth mechanism. Their development can be interpreted by either the classical internal oxidation theory or a short circuit diffusion model. The improved alloy/scale tenacity is discussed based on the fracture behavior of scales subjected to microindentation. 8 figures.
