Grain Refinement of Aluminium by Master Alloy AlTi6C1冯庆玲摘 要:<正> For the grain refinement of super pure aluminium and commercial pure aluminium,Al-Ti-C master al-loy is better than Al-Ti alloy.It was shown by scanning electron microscope(SEM)and electron-probe mi-croanalyser(EPMA)that when the amount of titanium added is less than 0.15%,grain......
Effect of Y Addition on Microstructure and Constituent Phases of Al-Ti-C Master Alloy许春香,卢斌峰,吕正玲,张金山,梁伟摘 要:Al-Ti-C master alloy was prepared by SHS (Self-propagating High temperature Synthesis)-melting technique. Effect of yttrium addition level on the microstructures of the master alloy was studied by XRD, SEM and EDS. The experimental results show......
