🔬 Exploring the Melting and Oxidation Behavior of Metal Alloys with STA Thermal Analysis
Metal alloys are widely used across many industries. Their melting temperature determines processing conditions, while oxidation behavior directly affects stability and service life in high-temperature environments. Understanding these thermal reactions is essential for optimizing alloy performance and expanding their applications.
In this study, a Simultaneous Thermal Analyzer (STA-1250S) was used to investigate the melting and oxidation processes of a metal alloy. The instrument offers precise temperature control and sensitive heat-flow detection, supporting measurements from room temperature up to 1250 °C.
During the test, the alloy sample was placed in an alumina crucible and heated from room temperature to 900 °C at 10 °C/min. The STA results revealed two distinct thermal peaks:
• 249 °C (ΔH = 6.7151 J/g): Corresponding to the melting process, where the alloy transitions from solid to liquid.
• 772 °C (ΔH = 3.6803 J/g): Associated with the oxidation reaction, where the alloy reacts with oxygen at elevated temperatures.
Thermal analysis provides a powerful tool for understanding material behavior. With precise measurement capabilities, instruments like the STA-1250S enable researchers to capture critical thermal events.
