本文利用Formaster相变仪对TiC—50Nb钢结硬质合金的TTT曲线进行了测定,其结果表明TiC—50Nb钢结硬质合金的TTT曲线分为二个“鼻子”区;合金中的碳化物及合金元素对TTT曲线形状有较大影响。
In this paper, the TTM curve of TiC-50Nb steel bonded carbide was measured by Formaster phase change instrument. The results show that the TTT curve of TiC-50Nb steel bonded carbide is divided into two “nose” regions. The carbide And alloying elements of TTT curve shape has a greater impact.
