摘　　要：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。TTT curve of TiC-50Nb steel bonded carbide was measured using the phase transformation device'Formaster' ,and results indicate that the TTT curve can be divided into two 'nose'zonea and that carbide and alloy elements have greater effects on the shape of TTT curve.

关 键 词：TiC-50Nb TTT曲线 钢结硬质合金
