Production and Tensile Behavior of Novel Powder Wire Mesh Composite Porous Plates

Abstract

A new type of powder wire mesh composite porous plate (PWMCPP) is successfully fabricated by the composite rolling and solid‐state sintering of stainless steel powder and wire mesh. Tensile tests are carried out, and the microstructure and fracture morphology are observed. The results show that the tensile strength of the PWMCPP decrease first and then increase with increasing mesh volume fraction and mesh diameter and increase with increasing sintering temperature. It is found that when the mesh volume fraction exceeds 65% and the sintering temperature exceeds 1310 °C, the tensile properties of the PWMCPP show the phenomenon of secondary plastic deformation work hardening with a saddle shape change. The tensile strength increased from 433 to 593 MPa, with an increase ratio of 36.95%, and the elongation increased from 33.17% to 55.7%, with an increase ratio of 67.92%. Herein, not only a method for preparing a composite of stainless steel powder and mesh is offered but also a useful reference for improving the tensile properties of the PWMCPP and expanding the application range (especially in the field of porous bearing) of porous metal materials is provided.
