尽管钢比钛几乎重一倍,但其强度和钛一样。钛合金比较难加工。由于钛的弹性模数是钢的60%,则加工钛材料时,刀具切削力要增加将近一倍,并且在刀具切过之后,材料还会反弹。钛的化学性能和热性能都对刀具不利,含钛的硬质合金与工件材料会起反应。此外,钛传导热特别慢,易产生粘附现象,因为粘附 Although steel is almost twice as heavy as titanium, it is as strong as titanium. Titanium alloy is more difficult to process. Since the modulus of elasticity of titanium is 60% of that of steel, the cutting force of the tool is almost doubled when the titanium material is processed, and the material will rebound after the tool is cut. Both the chemical and thermal properties of titanium are detrimental to the tool, and titanium-containing cemented carbide reacts with the workpiece material. In addition, titanium heat conduction is particularly slow, easy to produce adhesion phenomenon, because of adhesion
