Objective The Devonian bivalves are well developed, highly diversified and widely distributed in Guangxi. However, they have not been well studied previously, although several papers have dealt with it. Meanwhile, the biodiversity change of bivalves which is one of the most important benthos during Devonian in South China has not been studied yet. The aim of present project is focused on the study of systematic palaeontology, the life-habits, of Devonian bivalves of Guangxi.

The TiNw-AINp/Al composite has been successfully fabricated by gas-liquid reaction method in an intensive electromagnetic mixing and casting in an appropriate cooling condition. The as-cast samples of the composite exhibit a homogeneous distribution of TiNw and AINp, and the in situ formed TiN whisker has a mean diameter of 0.5 μm and mean aspect ratio of 5.8~7.5, and the diameter of the AIN particulates is less than 5 μm. TEM observation indicates that there exist some submicron and nanometer sized in situ formed TiNw-AINp in α-Al matrix. The formation mechanism of in situ formed TiNw and AINp is also discussed
