TCS不锈钢是一种含0.040wt.%Ti和0.096wt.%Nb的12wt.%Cr铁素体不锈钢。本文研究了TCS不锈钢在600~1300℃加热10min后再经水淬火后的组织和力学性能。结果表明，合金的抗拉强度和硬度均有所提高，但由于马氏体相的形成和晶粒的粗化，塑性和韧性有所下降。在未加热和加热的TCS不锈钢中，主要存在两种颗粒：尺寸为2-5μm的富钛颗粒和尺寸为20-50 nm的富Nb颗粒。
TCS stainless steel is a 12wt.% Cr ferritic stainless steel with 0.040wt.% Ti and 0.096wt.% Nb dual stabilization. This paper investigated the microstructures and mechanical properties of TCS stainless steel heated at 600–1300°C for 10min and followed water quenching. Results show the increasing of both tensile strength and hardness meanwhile the ductility and toughness have experienced the decreasing due to formation of martensitic phase and grain coarsening. In the unheated and heated TCS stainless steel, there are mainly two kinds of particles: Ti-rich particles in size of 2–5μm; Nb-rich particles in size of 20–50nm.
