一、概述TC11钛合金(Ti-6.5 Al-3.5Mo-1.5 Zr-0.3Si)是目前我国使用温变最高的两相热强钛台金之一,该合金是由 TC9发展而来。热强钛合金在较高温度下长期使用中组织和性能变化的规律一直是国内外十分关注的问题,通常把材料在空气中长时间热暴露后于常温或低温下保持塑性或韧性的能力,作为热稳定性的判据。根据资料,由于热稳定性的限制,BT9合金(与我国 TC11相当)在500℃下可靠工
First, an overview TC11 titanium alloy (Ti-6.5Al-3.5Mo-1.5Zr-0.3Si) is currently China’s use of two-phase hot-rolled high temperature titanium one of the strong, the alloy is derived from TC9. The law of the microstructure and properties of the hot-rolled titanium alloy under long-term use at high temperature has been a very important issue at home and abroad. The material generally retains plasticity or toughness at room temperature or under low temperature after prolonged heat exposure in the air, As a criterion for thermal stability. According to the information, due to thermal stability restrictions, BT9 alloy (equivalent to our TC11) Reliable at 500 ℃
