Abstract: The effects of chromium content,porosity and pore diameter on tensile property of GASAR porous Cu-Cr alloy were investigated.The results show that with the increase of porosity,the compression property of porous Cu and Cu-Cr alloys decreases,the yield strength and absorbed energy decrease,and the densification strain increases.The less the stress value of the compressed sample,the more easily plastic deformation could occur.Cr alloying can significantly improve the compressive properties of porous Cu-Cr alloys.Compared with porous Cu,the yield strength of porous Cu-1.3Cr alloys increases from 13 MPa to 32 MPa.The compressive properties of porous Cu-0.8Cr alloy decreases with the increase of pore diameter,and the yield strength and absorption energy decreases,then the plastic deformation is more likely to occur.
Key words: GASAR, Cu-Cr alloy, porosity, pore diameter, compression property
