... curves and construction of eutectic phase diagram. Source: Ref 6 Although not as common as the eutectic reaction, the peritectic reaction is another liquid-solid transformation that at first appears to be similar to the eutectic reaction but is actually very different. The silver-platinum system...

... similar to peritectic transformations, except that the initial phases are both solid. An example of a peritectoid transformation is provided by the formation of the intermetallic compound U 3 Si in uranium-silicon alloys. The relevant phase diagram is shown in Fig. 8.30 . Casting uranium at the proper...
