Thermophysical Properties of 60-NITINOL for Mechanical Component . . . The linear thermal expansion coefficient, specific heat capacity, electrical resistivity and thermal conductivity of 60-NITINOL were studied over a range of temperatures representing the operating environment of an oil-lubricated bearing
Experimental and numerical investigation of the transient thermal . . . Experiments were conducted to determine the thermal characteristics of the continuously twisted untwisted nitinol wires A heat conduction-based optimization model was built to determine the potential heating and cooling capacities (PHCCs) of the wires
The Effects of Cold Work and Heat Treatment on the Properties of . . . In this study the effects of heat treatments at 300-550°C for 2-180 minutes on Ti-50 8at%Ni wire with 30% and 50% initial cold work was investigated Transformational and mechanical properties were characterized through the BFR technique and tensile testing
Investigation of the impact of heat treatment on Nitinol wires This study aims to investigate a heat-treatment method that can reduce these uncertainties, ultimately narrowing down the precise and consistent austenite finish temperature for two types of Nitinol wire: a single wire and a coiled variant
Nitinol Technical Basic FAQ - Kelloggs Research Labs Every time you heat treat a nitinol wire, you change the transition temperature If the transition temperature is low enough, it won’t overcome the thermal hysteresis before reaching ambient temperature
