摘要

采用自蔓延高温合成-感应熔炼制备了原位TiBw/Ti复合材料

通过熔模铸造

成形了"┴"形和楔形钛基复合材料试样

测定了钛基复合材料的流动性能和充型能力。研究结果表明

与基体合金相比

钛基复合材料熔体的流动性降低了30%

钛基复合材料充满楔形试样的最小壁厚为0.30mm。提出了一种新的表征钛基复合材料充型能力的方法。经计算

在自由流动的情况下

原位TiBw/Ti复合材料熔体填充细小型腔的大小为0.975～2.460mm。

Abstract

In-situ TiBw/Ti composites were fabricated by SHS-induction melting.The fluidity and filling of the composites were evaluated

respectively

by pouring ⊥ shape and wedge shape samples in investment casting.It was found that compared with that of matrix alloy

fluidity of the Ti matrix composites is decreased by 30%

and the thinnest wall-thickness of wedge samples is 0.30 m.The new method to characterizing the filling of Ti matrix composites was put forward.The filling ability of in-situ TiBw/Ti composites was calculated in range of 0.975 m to 2.46 m in the condition of free flow.
