Microstructure and grain refining performance of a new Al–Ti–C–B master alloy

Effect of B/C ratio on the microstructure and grain refining efficiency of Al–Ti–C–B master alloy

“…The grain refining tests were carried out by adding 0.2% the prepared master alloys into 99.7% commercial pure Al with the same procedures [16]. The pictures of macrostructures were taken for each sample by a high scope video microscope (HSVM, KH-2200), and the average grain sizes were determined using the linear intercept method.…”

Influence of trace boron on the morphology of titanium carbide in an Al–Ti–C–B master alloy

“…For comparison, another Al-5Ti-0.25C master alloy was prepared using the same method and the same raw materials without Al-3B alloy. The preparation method of Al-5Ti-0.3C-0.2B has also been mentioned in our previous work [13]. First, Al ingot was melted and heated up to 1200 • C in a graphite clay crucible, and then appropriate amount of Ti, graphite powder (and Al-3B alloy for Al-5Ti-0.3C-0.2B) were added into the Al melt.…”

“…Especially, melt reaction method is one of the most popular means for the fabrication of effective Al-Ti-C (B) master alloys [4,5,13].…”

Investigation on Microstructure and Grain Refining Performance of a New Type of Al-3Ti-1C Master Alloy

“…The majority of the fine TiC particles are equiaxed and their surfaces are clear and regular. These have a large effect on grain refining efficiency [17]. Figure 5(a) shows the analysis of position 1.…”
