The impact test at elevated temperature of TiC particle reinforced Fe matrix composite prepared by self-propagating high-temperature synthesis method combined with pseudo hot isostatic pressing technique(SHS/PHIP) was carried out.

In situ formation TiC particles reinforced Fe-based alloy composite coating by GTAW;

TiC particles exhibit a continuous increase both in volume fraction and size from the bottom of the coating to the top surf.

2%CeO2 into the TiC strengthened steel resulted in significant refinement of TiC particles and more uniform distribution of TiC particles in the matrix,in comparison with the steel without CeO2 addition.

In situ synthesis of TiC-VC particles reinforced Fe-based metal matrix composite coating by laser cladding;

The results indicate that the induction clad composite coating is free from porous and microcracks and has a homogeneous microstructure consisting of TiC particles uniformly distributed in the eutectic matrix.

The high manganese steel matrix composites reinforced with in-situ TiC particles have been made by casting process successfully, the relationship between Ti content and its microstructure and mechanical (property) has been studied well.

It shows that the structure of TiC p/TIMETAL 62S consists of acicular alpha phase, little amount of beta phase and TiC particles; TiC particles can change matrix structure, and promote composite structure fine; this composite has good strength and ductility at room temperature, and good comprehensive effect.

Fabrication Technology for In-situ TiC Particulate Reinforced Cast Steel Matrix Composite;

The forming process of TiC particulates in molten Fe-Ti-C alloy has been studied.

The results show that metallographs show TiC particulates composed in basis which are small polygonal bulks.
