| description | In this paper， the preparation of Ni-Cr-Al alloy by the smelting process of 200 kg vacuum induction + vacuum arc remelting（VIM+VAR） was analyzed by means of tensile test at room temperature， optical microscope and hardness test （/%：0.01C， 0.10-0.20Si， 0.20~0.40Mn， 0.01P， 0.01S， 15.50Cr， 4.50Al， 3.00Fe， 0.005-0.01Y， 0.005-0.01Zr）. The influence of different pass deformation amount on the mechanical properties of Ni-Cr-Al alloy was studied. The experimental results show that the tensile strength， yield strength and Vickers hardness of the alloy increase gradually with the increase of accumulated cold drawing deformation， and the area reduction and elongation decrease gradually. When the deformation amount increases to a certain extent， the mechanical properties of alloy basically do not change.When the cumulative deformation of Ni-Cr-Al alloy reaches 78.7%， its performance is the best. The tensile strength at room temperature， yield strength， section shrinkage， elongation and Vickers hardness of Ni-Cr-Al alloy are 1 449 MPa， 1 130 MPa， 45%， 10% and 476， respectively. |
