多数镍基高温合金存在低塑性区,其温度范围为600～800℃,正处在材料使用温度范围内。它的存在影响了合金的使用,同时也限制了固溶强化和沉淀强化的热强化处理。因此研究镍基合金低塑性的本质,对于改善镍基合金具有实际意义。我们选择了典型的固溶强化镍基高温合金Hastalloy—x,对它的低塑性的本质进行了初步研究。
Most nickel-base superalloys have a low plasticity zone with a temperature range of 600 to 800 ° C and are in the material’s service temperature range. Its presence affects the use of the alloy and also limits the thermal strengthening of solution strengthening and precipitation hardening. Therefore, the study of the low plasticity of nickel-based alloys is of practical significance for the improvement of nickel-based alloys. We chose a typical solid solution strengthened nickel-based superalloy Hastalloy-x, its low plasticity of the nature of a preliminary study.
