It is a common practice to study the dependencies of the physical properties of alloys on the temperature and the composition without generalizing the results. It is more logical to study these dependences complexly, i.e., as fragments of “composit

All industrial alloys of the Al−Mg system correspond to the region of the α-solid solution of the phase diagram. Domestic alloys AL8 and AL27-1 and foreign alloys 520 (USA) and LM-10 (Great Britain) with a high magnesium content (9–11%) have hig

On the basis of an analysis of the heat transfer between samples and the surrounding medium, principles are formulated for the correct interpretation of the thermal curves in DTA. The influence of the type of phase transformation and the test conditi

A correspondence between certain transfer characteristic parameters is exposed by generalization of experimental data. The results may be used to analyze reliability of experimental data and to extrapolate the temperature dependence of thermal or ele

1. From the analysis of the spectral emissivity data at the wavelength of 0.65 millimicrons for refractory metals and alloys, an exponential temperature dependence has been established for the emissivity. 2. The proposed formula favors raising the ac

A method is described for determining thermal conductivity, based on solution of the nonlinear equations of heat conduction, for a quasisteady thermal state in the presence of a moving boundary. A formula is obtained for evaluating the time to establ
