摘要

含铝奥氏体钢（AFA 钢）有望用作液态金属冷却剂核反应堆的结构材料。研究人员在惰性环境中采用电弧熔炼法获得了六块铝含量可变的合金铸锭。经过均匀退火和轧制冷变形后，用获得的带材制作了用于机械测试和结构研究的样品，并在奥氏体钢的标准温度 1050 °С 下进行了最终退火。研究发现，当铝含量为 3.5 wt.% 时，屈服强度和极限拉伸强度达到最大值。值得注意的是，当铝含量增加到 4 wt.%时，强度和塑性都会降低。这种行为与钢的结构变化有关。

STRUCTURE AND PROPERTIES OF AFA STEEL FE-NI-CR-AL WITH VARIABLE ALUMINUM CONTENT

Aluminum-containing austenitic steels (AFA steels), which may be promising for use as structural materials in nuclear reactors with liquid metal coolant, are investigated. Six ingots of alloys with variable aluminum content were obtained by the method of arc melting in an inert environment. After homogenizing annealing and cold deformation by rolling, samples for mechanical tests and structural investigaion were made from the obtained strips, which were subjected to final annealing at the temperature standard for austenitic steels of 1050 °С. It was found that the maximum values of the yield strength and the ultimate tensile strength are observed at the aluminum content of 3.5 wt.%. It is significant that when the aluminum content is increased to 4 wt.%, the strengths and plasticity decrease. This behavior is associated with structural changes in steel.
