- W2390828376 abstract "NbC particulate reinforced spring steel matrix composite(NbCp/45CrMoV) was prepared by hot isostatic pressing(HIP),and its physical/mechanical properties had been investigated,including observing the microstructure,NbC distribution and the bonding interface of the composite,measuring the density,hardness,tensile strength,wear resistance of the composite,and analyzing the fracture behaviour and wear mechanism of the composite.Study results show that the composite has fine microstructure,uniform NbC distribution and good interface bonding between 45CrMoV matrix and NbC particles.The relative density,tensile strength,elongation,hardness,elastic modulus of the composite are 99%,1 250 MPa,2%,HRC 44,208 GPa,respectively.The wear resistance of the composite has greatly enhanced,especially under high load,the wear loss of NbCp/45CrMoV composite is only one quarter of the HIP 45CrMoV under load of 700 N,and the friction coefficient becomes greater." @default.
