    摘要:

    鈦合金薄壁構(gòu)件具有質(zhì)量輕、結(jié)構(gòu)緊湊等優(yōu)勢,然而因其軸向尺寸大、壁厚薄和形狀復(fù)雜等幾何特征,傳統(tǒng)成形技術(shù)在成形薄壁構(gòu)件時(shí)流程長、工藝復(fù)雜,嚴(yán)重限制了鈦合金薄壁構(gòu)件的應(yīng)用。金屬粉床3D打印技術(shù)可快速成形復(fù)雜異形零部件。為此,對電子束選區(qū)熔化技術(shù)(SEBM)和激光選區(qū)熔化技術(shù)(SLM)的成形能力和成形鈦合金薄壁構(gòu)件的微觀組織、力學(xué)性能和表面粗糙度進(jìn)行綜述,并分析3D打印高性能精密復(fù)雜整體鈦合金薄壁構(gòu)件的發(fā)展趨勢,為輕量化鈦合金薄壁構(gòu)件在高端裝備上的應(yīng)用提供參考。

    Abstract:

    Thin-walled components of titanium alloy are under the advantages of lightweight and compact structure.However,due to the geometric characteristics of large axial dimensions,thin-wall thickness and complex shapes,traditional forming techniques has a long and complicated process when forming thin-walled components,which severely limited the application of thin-walled parts. The 3 D printing technology can quickly manufacture the complex specialshaped components. The forming capabilities of selective electron beam melting( SEBM) and selective laser melting( SLM) and the microstructure,mechanical properties and surface roughness of titanium alloy thin-walled components were reviewed. The development trend of precision and complex integral thin-walled components of titanium alloy made by 3 D printing was analyzed,providing reference for the application of lightweight titanium alloy thin-walled components in high-end equipment.
