초록

Gas-permeable metal die materials are developed using tool steel powder, packed in a mold having the insertion of orthogonally arrayed polymer wires. Linear gas-permeable channels in orthogonal array are thus developed by the burning out of the polymer wires, which yield a microstructure with wear resistance value and air permeability much larger than those of the conventional gas-permeable die material.
