Method for branch crystal balling in large block metal glass composite

Method for predicting wettability of low melting point element-regulated hard solder

The invention discloses a method for predicting the wettability of a low melting point element-regulated hard solder. The method comprises the following steps: 1, measuring the contents WM% (mass fraction) of all low melting point elements in the solder; 2, determining the melting temperature range delta TM of the solder; 3, expanding the contents WM%, obtained in the step 1, of the elements having different low melting points by 100 times, respectively substituting data of the melting temperature range delta TM, obtained in the step 2, into a predictive mathematical model SM, and multiplying to obtain the numerical value of the SM; 4, judging the wettability of the solder according to the numerical value of the SM, wherein the smaller the numerical value is, the better the wettability of the solder is, and the higher the numerical value is, the poorer the wettability of the solder is. The method can be used for rapidly efficiently and accurately predicting the wettability of the low melting ...

Method for branch crystal balling in large block metal glass composite

This invention relates to the method for producing plastification geode/massive metal glass composite material. The steps are: first, selecting alloy components having strong glass formation ability, regulating the components to make them offset eutectic point, and solid solution phase being separated earlier; second, the components being smelted under shield gas, then producing foundry alloy ingot; then, said ingots being broken, resmelted, subjected to low pressure casting/water-cooling copper mould quick cooling formation to produce branch like crystal/massive metal glass composite material sheet, finally, said sheet being subjected to isothermal treatment and then water-quenching to produce this invented product. The plastificiation beta phase is no longer having branch like shape but having ball shape.
