Abstract

1486964 Sintered boride containing alloy TOYO KOHAN CO Ltd 27 Feb 1975 8243/75 Headings C7A and C7D A sintered alloy comprises: B 3-20% at least 1% of at least one of Cu, Co, Cr, Hf, Mo, Nb, Ni, Ta, Ti, V, W and Zr, and at least 20% Fe as the balance, apart from impurities and incidental elements, (e.g. small amounts of Si and impurity amounts of Al, C and N) and has a microstructure having a hard multiple boride phase containing iron with a metal or alloy phase. The boron may be provided as a plain or substituted iron boride, which may be prepared by water- or gas-atomizing; the powder mixture may be mixed in a ball mill or vibratory ball mill and pressed hot or cold in a press or isostatically; and the green compact may be sintered by an electro-discharge sintering process (e.g. pressing the powder while passing an electric current therethrough while filled between two graphite moulds).
