An Overview on the Indium–Thallium (In–Tl) Shape Memory Alloy Nanowires

Abstract

The binary indium-thallium (In-Tl) alloy is a classic type of shape memory alloy with a low melting temperature. In-Tl nanowires (NWs) were prepared by a simple mechanical injection of liquid metal method using anodized aluminum oxide (AAO) as a template. Sample preparation procedures are given in detail, including the AAO fabrication and mechanical injection techniques. Transmission electron microscopy (TEM) was utilized to characterize the NWs. It was revealed that the NWs were composed of polycrystals with high crystallinity. By in situ heating the NWs in the TEM, reversible transformations between the parent and the martensite phases were observed in both large and small NWs.

Investigation on thermo-physical properties of liquid In-Tl alloy

“…Small amount of indium is used to improve the machinability of gold alloys for jewelry [1].The indium-thallium alloy is a classic type of shape memory alloy with a low melting temperature. It has wide range of practical applications in the field of metallurgy which includes the use in thermostats, hydraulic lines and electrical circuits [2]. Thallium alone is improper for direct use because of its properties of toxicity, unfavorable mechanical properties and significant tendency to oxidize.…”

Thermodynamic, Structural, Surface and Transport Properties of In-Tl Liquid Alloy at Different Temperatures

“…The binary In-Tl alloy has widely been studied in the past because of its wide range of practical applications [10] [11] [12]. It is a shape memory alloy [13] having low melting temperature (fusible alloy).…”
