An interesting phenomenon that yielding was observed in the Ti matrix composites with above 4.10vol%TiCp. To clarify the underlying nature, in-situ tensile test was performed, and results indicated that this was caused by cracking at the interface between the aggregated TiCp and Ti matrix, which is quite different from the well-accepted viewpoint. Furthermore, fracture of stronger TiCp prior to weaker TiBw was also found during in-situ tensile test, and a fracture criterion was proposed from the viewpoint of load transfer.

粉末冶金(TiC p + TiB w)/ Ti复合材料中明显的屈服现象和选择性断裂行为

一个有趣的现象是,在TiC p大于4.10vol%的Ti基复合材料中观察到屈服。为了弄清其基本性质,进行了原位拉伸试验,结果表明这是由于聚集的TiC p和Ti基体之间的界面开裂引起的,这与公认的观点大不相同。此外,在原位拉伸试验中,还发现了较弱的TiB w之前的较强TiC p的断裂,并且从载荷传递的角度提出了断裂准则。
