A cardiovascular stent is a medical device to open a plaque-blocked vessel. A commonly-used material for stents is Nitinol, a Nickel and Titanium alloy. During the manufacturing process, a stent is annealed and quenched into a specific shape. The annealing process is a heat treatment that keeps the stent under high temperature for a certain time, and the quenching process submerges the stent into a quenchant to cool it at a certain rate. The cooling rate of a stent should be controlled, as too slow of cooling rate is inefficient for the manufacturing process, and too fast of cooling rate can increase the brittleness of the stent, which can cause heat-induced stress and even cracking. In this simulation, we model the quenching process of an annealed stent and study how different quenchants affect the cooling process. For this, we will use a Transient Thermal Analysis to understand the time-dependent response of the stent.
