Influences of Molybdenum and Rare Earth on Mechanical Properties of ZG30Cr

Alloying is an important method to improve properties of casts. The influences of Mo and RE on the mechanical properties of ZG30Cr were investigated in this work. A good comprehensive mechanical properties of the alloy with 0.3% Mo and 0.1% RE were obtained. The elongation, tensile strength, impact toughness and hardness of the alloy reaches 7. 21%, 577.49 MPa, 91.7 J·cm−2 and HRC 24.6, respectively.
