Effect of Vacuum Induction Melting Frequency on NiTi Shape Memory Alloy
Effect of Vacuum Induction Melting Frequency on Nickel-Titanium Shape Memory Alloy
Abstract
NiTi shape memory alloys (SMAs) are known for their ability to remembers their original shape after the removal of external forces. Currently, vacuum induction melting (VIM) process is used to produce NiT......
Unsteady Flow Field and Influencing Factors in Friction Stir Welding Process
Abstract
This article aims to explore the unsteady flow field and influencing factors of mixing, friction, and welding process. Firstly, the measured unsteady pressure signal and the turbulence kinetic energy data were compared with the existing theoretical models and then discussed. Finally, thi......
Crystallizer Vibration Parameters
Crystallizers are a type of process equipment which are used to perform a variety of solid/liquid separation or crystal size refinement processes in the chemical and petrochemical industries. Crystallizers, like other processing machines, must be accurately tuned and monitored to ensure optimal pe......
Steel most sensitive to cracks
Introduction
Crack locations in steel structures are of utmost importance in order to prevent major structural failures. In order to reduce the risk of such failures, it is highly important to develop effective and reliable crack detection methods. The use of ultrasonic testing (UT) is a well-kno......
