用高速钢、硬质合金车刀车削镍基合金(例如Inconel 718、Hastelloys和Waspaloy等),钴基合金(例如Stellite和Mar-M302等)和铁基合金(例如incoloy、A-286和Greek、Ascoloys)等奥氏体高温合金是切削领域中的最大难题之一。这是因为含有铝、钛、铌等γ相形成元素和钼、
Nickel-based alloys such as Inconel 718, Hastelloys and Waspaloy, cobalt-based alloys such as Stellite and Mar-M 302, and iron-based alloys such as incoloy, A-286 and Greek, Ascoloys and other austenitic superalloys are one of the biggest challenges in the field of cutting. This is because it contains γ-phase forming elements such as aluminum, titanium and niobium and molybdenum,
