【摘要】：作為一種功能性鈦合金,Ti40阻燃鈦合金的熱物理性能數(shù)據(jù)首次被報道。采用真空自耗電弧熔煉技術(shù)制備的Ti40合金鑄錠成分均勻,利用熱擠壓開坯+包套保護(hù)鍛造方法制備的板坯組織均勻。性能測試結(jié)果表明:Ti40合金的室溫抗拉強度為950 MPa級,且在500℃下具有良好的熱暴露性能、高溫蠕變性能和高溫持久性能。在室溫到600℃范圍內(nèi),合金的楊氏模量和剪切模量隨著溫度的升高呈線性下降,泊松比隨著溫度升高而緩慢增加;線性熱膨脹曲線隨著溫度升高呈拋物線增加,平均線膨脹系數(shù)隨著溫度的升高呈線性增加。
[Abstract]:As a functional titanium alloy, the thermal physical properties of Ti40 flame retardant titanium alloy are reported for the first time. The composition of Ti40 alloy ingot prepared by vacuum consumable arc melting technology is uniform, and the structure of slab prepared by hot extrusion open billet jacket protection forging method is uniform. The results show that the tensile strength of Ti40 alloy is 950 MPa at room temperature, and it has good thermal exposure property, high temperature creep property and high temperature rupture property at 500 鈩，
