Prediction of amorphous forming ability based on artificial neural network and convolutional neural network

Using a trial and error method to measure amorphous forming ability in the experiment is a complex and time-consuming process. Therefore, it is necessary to devise a method that can rapidly and accurately predict the amorphous forming ability. In this study, two models, artificial neural network and convolutional neural network, are proposed for the prediction of amorphous forming ability of various amorphous alloys. The prediction accuracy of the two models reached 0.77623 and 0.71693, respectively, both of which were more than 19% higher than the reported prediction accuracy of the 13 criteria. This result shows that artificial neural network and convolutional neural network models can accurately predict the amorphous forming ability of a variety of amorphous alloys and provide theoretical guidance for the development and preparation of amorphous alloys.

Preparation of amorphous alloys in Zr–Mo–Pd system

All boundary systems of the Zr–Mo–Pd system show at least one eutectic. This indicates the existence of low melting temperature (~1000°C) eutectic alloys in this ternary system, and is therefore directly related to the possibility of glass formation. Some amorphous and microcrystalline ternary samples were prepared via rapid solidification (~106 K s−1 ) in a splat cooling apparatus with a radio frequency levitation coil and a high velocity two piston arrangement driven by solenoids. To obtain the starting material, homogeneous Zr–Mo–Pd samples of differing composition were prepared via arc melting techniques. Some amorphous alloys have also been obtained in the Zr–Pd–(Si,B) systems.MST/1662

Preparation and properties of amorphous CdTe

The preparation of amorphous alloys of CdTe by vacuum deposition and the effects on the resulting films of using different sources are described. When using a flash evaporation source, it is shown that the source material must contain ~10% excess cadmium by weight to produce a purely amorphous film with a near-stoichiometric ratio of Cd to Te. Optical measurements on Cd and Te alloys are presented together with some Seebeck and conductivity data, with special emphasis on near-stoichiometric amorphous CdTe and a partial band diagram is given for this latter material.
