Directional solidified cu - cr in - situ composites have high strength, high electricity but without such problems of interfacial contamination and low stability as in the conventional man - made synthetic composites due to self - driven engender in the process of directional solidification, so this composites are expected to be used as contact cable, which is made for trunk line electrification
定向凝固cu - cr自生復合材料由於具有高強度、高導電性，同時因其在凝固過程中自動形成而避免了人工復合材料中長期存在的界面污染、穩定性差等不足，因而在電氣化鐵路用電車線材方面有廣闊的應用前景。
