摘要: 研究了超塑合金Ti-12Co-5Al非平衡態β相α+Ti₂Co共析轉變的時效過程以及它的硬度變化。當溫度為450℃時,隨著時間的增長硬度隨之增加,β相的轉變也更加完全,轉變產物之間以及轉變產物與母相之間的相變也從完全共格到半共格再到完全非共格,而峰值發生在320min左右;當時間為20min時,隨溫度的升高也具有相同的規律,峰值發生在600℃左右。Al元素除了具有固溶強化的作用之外,還有提高共析相變溫度,從而減緩了相轉變動力學的進行。

Abstract: Ageing process and its hardness change from β to α+Ti₂Co of alloy Ti-12Co-5Al were investigated. At 450℃,the amount of transformation increases with ageing time and the boundary between the transformation product and the matrix changes from coherent to incoherent. The maximum hardness is achieved at around 320 minutes. With the same ageing time of 20 minutes, the same thing happens as above with increasing temperatures and the hardness peaks at around 600℃.The addition of element aluminum slows down the kinetics of ageing transformation in addition to its strengthening effect.
