“…The tendency of d to be proportional to T and t is in good agreement with previous results, [18] demonstrating that an increase in T and t facilitates an increase in the diffusion velocity and amount, respectively. Dense TiC ceramic layers have also been observed to thicken with increasing T and t, leading to increased oxidation resistance [19]…”

We report the in situ synthesis of a dense TiC ceramic layer between a titanium plate and graphite flakes in gray cast iron using heat treatment. The phases of the dense ceramic layer were determined by XRD, and the microstructures of the layer were characterized by SEM. The kinetics of the layer were also analyzed. The particle sizes of the as-prepared TiC samples varied from 1 mm to 10 mm. The thicknesses (d) of the layers, which increased gradually with incubation time, were 46, 65, 80, 96, and 110 mm after 1, 2, 3, 4, and 5 h of incubation at 1433 K, respectively. The formation of the dense layer involves diffusion, an in situ reaction, and the diffusion of C, Ti, and TiC atoms. The d of the layer changed parabolically with time, and the relationships between d, T, and t were determined.

“…To increase the strength and conductivity of the material, many researchers have conducted numerous studies on the alloying by the addition of other elements in binary Cu-Fe alloy [1][2][3][4][5][6][7][8]. Due to the extremely low solid solubility (0.0133 wt.%) of C in copper matrix [9], C is seldom added as the alloying element of copper alloys in existing research. Hyung Giun Kim [9,10] and E Jeong [11] et al studied the effect of addition of trace amounts of C (0.0133 wt.% and 0.05wt.%) on the microstructures of Cu-2.5Fe-0.1P.…”

They found that the addition of C increased the tensile strength and conductivity of Cu-2.5Fe-0.1P alloy by refining the Fe phase and the precipitated Fe3P particles and reducing the solid solubility of Fe atom in the copper matrix.…”

The effect of C addition on the microstructure of a Cu-Fe alloy was investigated by combining the calculation of phase diagram (calphad) and the experimental research. The calphad results indicated that the addition of C substantially enlarged the zone of liquid immiscibility gap in the metastable phase diagram of Cu-Fe alloy. In addition, the larger the addition content of C was, the more obvious the phenomenon was. As a result, the presence of trace amounts of C in the Cu-Fe alloy containing 5~20% (wt.) Fe would cause the liquid phase separation of Cu-rich and Fe-rich liquid phases during the solidification process of the alloy. The experimental results showed that the dendritic secondary phase in the as-cast microstructure of the Cu-14Fe alloy tended to be spheroidized after the addition of C due to the separation of Cu-rich and Fe-rich liquid phases. With the increasing content of C, the volume fraction and the average diameter of the spherical Fe-rich particles both increased. The calphad conclusions are in agreement with the experimental results.

“…For commercial purpose, optimization of mechanical properties to electrical conductivity can be achieved by means of alloying elements and thermo-mechanical treatment. Many studies have been devoted to the effects of alloying elements on the Cu matrix, such as boron (B), cerium (Ce), silver (Ag), cobalt (Co), beryllium (Be), chromium (Cr), ferrous (Fe), phosphorus (P), titanium (Ti) and others [1][2][3][4][5][6][7][8][9][10]. Thereafter, the effects of these elements on the properties and structures of Cu matrix have been studied.…”

In situ synchrotron X-ray diffraction was used to study a deformed Cu-0.88 Fe-0.24 P alloy during heating process. The measurements were performed at room temperature and also at high temperatures up to 893 K in order to determine the recovery, ageing and recrystallization process. With the increase of temperature, the angles of copper matrix peaks moved left and the FWHM (full width at half maximum) decreased slightly. Fe3P precipitates were first detected at 533 K, reached the maximum at 673 K, and re-dissolved into matrix at 853 K. A dramatic decrease in FWHM was observed accompanied by the precipitation of Fe3P phases, indicating the reduction of lattice distortion of copper matrix.
