摘要
综述了采用多种表征手段和测试方法对GH3536合金在冷变形过程中的变形行为及形变机制进行的详细研究。此外,通过模拟计算揭示了层错能对形变机制的调控作用和形变孪晶的取向依赖性。试验发现,GH3536合金与最近发展的具有面心立方结构的高熵合金类似,具有非凡的低温性能。在低温加载时,合金的强度和塑性同时增加,这大大增强了合金的可加工性能。
The deformation behavior and deformation mechanism of GH3536 superalloy during cold deformation were meticulously investigated with diverse characterized means and testing methods are described.Moreover,the regulating effect of stacking fault energy on deformation mechanism and the orientation dependence of deformation twinning are revealed by means of simulated calculation.It is found through the tests that GH3536 alloy has extraordinary cryogenic properties,similar to the recently developed face-centered cubic high-entropy alloys.The strength and plasticity of the alloy increased simultaneously during loading at cryogenic temperature,which indicates an improved processibility.
