飞机起落架用ZG-28铸钢组织和性能的研究

INVESTIGATIONS ON MICROSTRUCTURES AND PROPERTIES OF CAST STEEL ZG-28 IN AIRCRAFT LANDING GEAR

本文研究了ZG-28的组织和性能,结果表明这种铸钢具有很高的强度,良好的塑性和韧性,其断裂韧性和几何物理塑性系数均优于30NFCHA合金,可以用于飞机的重要受力构件。

The paper is about the research on the microstructures and properties of cast steel ZG-28. The results demonstrate that the cast steel has bight tensile strength, ductility and toughness, better fracture toughness and geometrical physical ductility coefficients than those of alloy 30XFCHA. It can be applied in key bearing components in aircrafts.
