Is it possible, given a target temperature, to create an alloy that melts at precisely that temperature?

Assuming the target melting points are between the melting points of mercury and tungsten, is it possible, given a target temperature, to create an alloy (or compound) composition that has a direct (say eutectic) transformation to liquid at +/- one degree of the target temperature?


If yes, is there a method for identifying the elements to use based on the target temperature?
