最新的校园时光歌曲:急!求高手帮忙翻译一下论文摘要。
GH4586B合金就是在GH4586A的基础上通过成分微调形成的,以期不析出TCP相。本次实验主要研究在不同的长期时效处理制度下,GH4586A合金的拉伸性能与微观组织的变化情况。再通过透射电镜、扫描电镜的观察,得出显微组织的形貌、数量、大小和分布,分析它们与力学性能的关系。为合金的成功应用提供可靠的依据。

Along with our country astronautics enterprise development, is more and more high to the heat-resisting alloy performance requirement, the
precipitation hardening nickel base distorts the GH4586 alloy is for satisfy, it which astronautics industry the development develops is used in the 120T thrust-augmented rocket turbine disk material,
satisfies the alloy in 800-850 ℃ sector strength at high temperatures and the long-term strength request, is our country "75" "85" as well as "15" the key attack topic, holds the importantposition in our country astronautics with the heat-resisting alloy in.
The GH4586B alloy is forms in the GH4586A oundation through the ingredient trimming, does not separate out TCP by the time. This experimental main esearch under different long-term aging treatment of metal system, GH4586A alloy stretch performance and microscopic organization's change situation. Again through passes the radio mirror, the scanning electricity mirror observation, obtains the
microstructure the appearance, the quantity, the size and the distribution, analyzes them and mechanics performance relations.Provides the reliable basis for the alloy success application.
