    • The mould (10) includes at least one part (20), intended to be in contact with the component (12) being moulded, made from sintered vitreous silica. According to the process, said component (12) is formed by the superplastic forming in the mould (10) of a plate (18) made of a material capable of undergoing superplastic deformation, for example titanium or titanium alloy, aluminium or aluminium alloy, or any material exhibiting superplastic properties. Preferably, a barrier is formed between at least a part of the contact surfaces of the mould (10) and the component (12) being moulded, for example by coating with boron nitride, at least partially, the contact surfaces of the mould (10) and the component (12) being moulded, before placing the plate (18) in the mould (10), and/or by injecting an inert gas, notably helium or argon, between the contact surfaces of the mould (10) and the component (12) being moulded.
    • 模具(10)包括至少一个部分(20),其旨在与被模制的组件(12)接触,由烧结玻璃状二氧化硅制成。 根据该方法,所述部件(12)通过在由能够经历超塑性变形的材料(例如钛或钛合金,铝或铝合金)制成的板(18)的模具(10)中形成超塑性, 或任何具有超塑性的材料。 优选地,在模具(10)的接触表面的至少一部分和被模制的部件(12)之间形成阻挡层,例如通过用氮化硼至少部分地涂覆模具(10)的接触表面 )和组件(12)在将板(18)放置在模具(10)中之前,和/或通过在模具(10)的接触表面与模具(10)的接触表面之间注入惰性气体,特别是氦或氩 组件(12)被模制。
