为了研究钒合金的低温脆化行为，对V <$Cr <$Ti和V <$Fe <$Ti合金进行了夏比冲击试验和拉伸试验。这些在1100°C下退火的合金代表室温附近的韧脆转变温度，转变（DBTT）。然而，通过优化热处理条件，DBTT转移到低温和液氮温度以下。另一方面，钒合金的拉伸试验在低至-196 °C下没有显示出脆性行为。这种差异可能是由于合金的晶粒尺寸或织构不同造成的。讨论了钒合金的最佳热处理工艺条件和脆性行为。
In order to investigate the low temperature embrittlement behavior of vanadium alloys, Charpy impact tests and tensile tests were performed for VCrTi and VFeTi alloys. These alloys annealed at 1100°C represent the ductile-brittle transition temperature, transition (DBTT) around room temperature. However, by optimising the heat treatment condition, DBTT shifts to low temperature and below liquid nitrogen temperature. On the other hand, tensile tests of vanadium alloys did not show the brittle behavior down to — 196°C. This discrepancy is probably caused by the different grain size or texture of the alloys. The optimal thermal treatment condition and embrittlement behavior of vanadium alloys are discussed.
