PURE TITANIUM/TITANIUM ALLOY CLAD CUTTER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pure titanium/titanium alloy clad cutter which is light, rich in its sharpness and durable sharpness, hardly generates the breakage or damage of the cutter and has no difficulty resulting from metal ions and a method for producing it.;SOLUTION: Strucurally, a means for composing a core material layer conencted to a cutting edge part of α+β type titanium alloy and covering at least one side surface of the core material layer with α type pure titanium is employed. Further, as a method, α+β type titanium alloy is connected to αtype pure titanium by a hot rolling method to obtain an intermediate rolled plate. The intermediate rolled plate is subjected to a cold rolling process under the rolling reduction rate of 40% or higher so that its thickness is reduced under rolling to the desired thickness of the cutter to form a raw material plate with Hv of 520 or more. A prescribed work is applied to the raw material plate to form the cutter.;COPYRIGHT: (C)2002,JPO
