用穆斯堡尔谱研究了ZG0Cr13Mn10N钢气蚀(CE)前后的表面组织变化。结果表明,ZG0Cr13Mn10N钢气蚀前主要由亚稳定的合金奥氏体及内磁场值分别为23395.8kA/m和21088.0kA/m的两类合金马氏体组成;气蚀诱发γ/α转变的同时还明显改变材料表层组织中合金元素的相内分布形式,并诱发出一种合金度更高的合金马氏体(其内磁场值为18462.0kA/m)。
Mossbauer spectroscopy was used to study the surface texture changes of ZG0Cr13Mn10N before and after cavitation (CE). The results show that before cavitation, the microstructure of ZG0Cr13Mn10N steel is dominated by two types of alloy martensite including the metastable alloy austenite and internal magnetic field of 23395.8kA / m and 21088.0kA / m, respectively. Cavitation induced γ / α At the same time, the phase distribution of the alloying elements in the surface layer of the material was obviously changed, and an alloy martensite with a higher alloyed degree (the magnetic field value was 18462.0kA / m) was induced.
