“…A further increase in sodium concentration has little effect. In Figure 3, the results of Pugachevich (1959) for Hg + N a and Hg + Cs are compared with those of the present study; the present values are much lower. Although the different approach in the experiment may have somewhat contributed to the discrepancy, it would hardly account for all disagreement.…”

The surface tension of pure mercury and mercury containing up to 0.2 weight % sodium has been investigated between about 20' and 350' C., by the method of maximum bubble pressure. The present results for pure mercury are in good agreement with those previously reported, and an empirical correlation is presented as a function of temperature. Even a trace of sodium in mercury seems to lower the surface tension markedly and at a sodium concentration of only 0.04 weight YO, the surface tension is reduced to about 60% of that of pure mercury.A further increase in sodium concentration has little effect. The effect of the elevated temperature is of secondary importance in mercury containing dissolved sodium.

“…This increase in meltpool temperature leads to spreading and vaporisation of melted powder from the meltpool causing reduced height of track. 18 It can be inferred from Figure 4 that track height increases with the reduction in scan speed. This is primarily due to an increase in the interaction time between powder/substrate and laser beam at lower values of scan speed, which causes more melt and higher deposit.…”

Laser additive manufacturing using directed energy deposition (LAM-DED) technique is one of the recent techniques for fabricating engineering components directly from 3D CAD model data using high power lasers. In this respect, LAM-DED of copper (Cu) and stainless steel (SS) is an enduring research area. However, LAM-DED of Cu is challenging due to higher thermal conductivity, lower absorption to infrared radiation and oxide formation tendency. The present work reports an experimental investigation to evaluate the effect of process parameters on the track geometry, contact angle, inter-diffusion and micro-hardness of Cu tracks deposited on SS 304L substrate using LAM-DED. Analysis of variance is used to estimate the contribution percentage of process parameters on the track geometry. Further, Cu bulk structures are deposited at an identified combination of process parameters and they are subjected to optical microscopy for microstructural characterisation. Further, finite-element-based numerical simulation is performed to understand the temperature distribution during the processing of Cu bulk structures on SS304L and the temperature results are co-related with the microstructural transformation during the processing. This investigation paves a way to understand the effect of processing parameters for building Cu bulk structures on SS Substrate using LAM-DED.

“…The quality of the predictions of different surface tension models is tested with five ternary systems published in the literature [8][9][10][11][12][13]. The ternary mixtures of cyclohexane/benzene/chlorobenzene, cyclohexane/toluene/chlorobenzene, n-hexane/n-octane/n-tetradecane, and cyclohexane/benzene/n-hexane are used as models for near-ideal mixtures, with the ternary liquid ethanol/glycerin/water mixture serving as a model for a nonideal ternary mixture with considerable differences in surface tension.…”

The utilization of excess quantities as the basis of a thermodynamic approach can simplify the prediction of multicomponent data from binary ones. Whereas in Part II the excess formalism was applied to the prediction of liquid phase adsorption on solids, in this paper, the liquid/air interface is investigated. In order to show the generality of the suggested approach, thermodynamic equations are developed in analogy to Part II. Surface tensions are predicted by different excess models and compared with experimental data. From predicted surface tensions, ternary adsorption isotherms on the liquid/air interface are calculated.
