“…The importance of the manner in which different elements are combined in steels is gaining increased recognition. Most of the published work over the past year on methods for isolating compounds from steel for study has described procedures for the separation, analysis, and identification of carbides (6,11,29,37, 39, 54-57, 62, 63, 72-75, 77, 78, 94). Most of these involved electroly'sis with an aqueous electrolyte.…”

PRACTICALadvances in ferrous analytical chemistry result from a correlation of available information with experience in selecting the most likely approach to solution of a specific problem. Frequently these advances are made under the compulsion of need for new or better data on experimental operations or new experimental alloys, and the chemist utilizes the store of basic information in the literature along with new reagents and tools as a basis for devising the method best suited to his requirements and the working facilities at his disposal.

Fabrication with the in-situ formation of W2C reinforced medium carbon steel (MCS) MMC’s was attempted using W or WO3 and graphite addition to steel. The P/M route comprising milling, compaction and sintering at 1050 °C and 1120 °C respectively in 90% N2 + 10% H2 atmosphere was adopted. Both SEM and BET studies revealed the particle size to be around 100, 7 and 40 µm for MCS, W and WO3, respectively. A complete conversion of tungsten into tungsten semicarbide (W2C) was noted in XRD for the tungsten additions of ∼6, 9 and 12 wt.% with stoichiometrically balanced C (graphite) addition of 0, 0.2 and 0.4 wt.%. However, WO3 + C addition (balanced as above) revealed the partial conversion of WO3 to W2C. The peaks of Fe3C were observed only for MCS + W + C samples and not for MCS + WO3 + C samples in XRD. In SEM, the WO3 phase appeared porous and partially converted, whereas, W2C phase was dense. Sintered density improved for the addition of W, whereas it monotonically reduced for WO3 addition to MCS + C samples. Higher hardness, compressive strength, and wear resistance was noted for W addition than WO3 to MCS+C samples.
