  • METHOD OF PREPARING ALUMINUM MATRIX COMPOSITES AND ALUMINUM MATRIX COMPOSITES PREPARED BY USING THE SAME
    Publication number: 20140037494
    Abstract: A method of stably preparing an aluminum composite with excellent mechanical properties while the temperature of molten aluminum is maintained at 950° C. or less, includes mixing aluminum powder, a source material for titanium, a source material for a nonmetallic element that is able to be combined with titanium to form a compound, and an active material to prepare a precursor; adding the precursor to molten aluminum; and casting the molten aluminum.

  • PROCESS FOR MAKING TI-NI BASED FUNCTIONALLY GRADED ALLOYS AND TI-NI BASED FUNCTIONALLY GRADED ALLOYS PRODUCED THEREBY
    Publication number: 20090071577
    Abstract: The present invention relates to Ti—Ni based functionally graded alloys easy in proportional control, which are made by cold working and annealing Ti—Ni based alloys under a predetermined temperature gradient. The thus processed Ti—Ni based functionally graded alloys have a shape memory effect and an ultra elasticity and at the same time, have a consecutive variation of shape depending on a temperature variation.
