α+β钛合金【Ti-6Al-4v钛板】TC4钛合金性能
A titanium alloy: it is alpha solid solution consisting of A single phase alloy, both in the practical application of general temperature or at higher temperatures, are the alpha, organizational stability, abrasion resistance higher than that of pure titanium, antioxidant ability. Under the temperature of 500 ℃ ~ 600 ℃, still maintain its strength and creep resistance, but not for strengthening heat treatment, strength at room temperature is not high.
TC4材料固溶强化处理后,强度增加不大,也就到1100MPa,退火状态下强度一般在900MPa
TC4 热膨胀系数:
TC4钛合金具有X良的耐蚀性、小的密度、高的比强度及较好的韧性和焊接性等一系列X点,在航空航天、石油化工、造船、汽车,医药等部门都得到成功的应用。TC4钛合金力学性能:抗拉强度σb/MPa≥895,规定残余伸长应力σr0.2/MPa≥825,伸长率δ5(%)≥10,断面收缩率ψ(%)≥25
