抄録

In the investigation of cast materials, the authors found the following: When the castings made of pig iron containing titanium had parts very different in thickness, they were apt to have casting defects analogous to pin holes and showed low values in water-pressure-resistance test. To make clear the sause of this defect, firstly, the configuration of Ti compounds in the synthetic titanium pig iron was studied by X-ray diffraction method. The results obtained were as follows: (1) Titanium compounds in the synthetic pig iron (Ti<0.7%) consisted in two TiN-TiC solid solutions, namely TiC containing little TiN and TiN containing a considerable amount of TiC. The former is called TiC(N) and the latter, TiN(C) in this report. (2) TiN(C) existed in pig iron containing Ti below 0.3%. Its lattice constant was increased linearly with increase of Ti content. (3) In low Ti pig iron,there were more TiN(C) than TiC(N), but TiC(N) was increased with increase Ti content. Only TiC(N) existed in pig iron containing Ti above 0.30%.
