IMI834钛合金和2219-O铝合金的金相组织分析

Microstructure Analysis of IMI834 Titanium Alloy and 2219-O Aluminum Alloy

钛合金和铝合金在航空航天领域应用十分广泛,尤其是飞机上所用的各种零件等。本文从IMI834钛合金和2219-O铝合金入手,利用金相显微镜分析了钛合金的等轴组织、双态组织和Widmanst tten组织,以及2219-O铝合金的原始组织、一道次组织和多道次组织。

Titanium alloy and aluminum alloy are widely used in the aerospace field,especially in various parts of the aircraft.Starting with IMI834 alloy and 2219-O alloy,the equiaxed,bimodal and Widmanst tten structures of titanium alloys,as well as the primary,primary and multi-pass structures of 2219-O alloy were analyzed by metallography.
