Nickel titanium alloy is a metal material with excellent properties, which has attracted much attention due to its unique shape memory effect and superelasticity. This article will provide a detailed introduction to the composition, preparation methods, performance characteristics, and application fields of nickel titanium alloys.
1. Composition of nickel titanium alloy
Nickel titanium alloy is mainly composed of two metal elements: nickel (Ni) and titanium (Ti). According to different ratios and preparation processes, nickel titanium alloys can be classified into different types, such as Ni Ti binary alloys, Ni Ti X ternary alloys, etc. Among them, Ni Ti binary alloy is the most commonly used nickel titanium alloy.
2. Preparation method of nickel titanium alloy
Powder metallurgy method
Powder metallurgy is one of the main methods for preparing nickel titanium alloys. This method involves mixing nickel powder and titanium powder in a certain proportion, then hot pressing or hot isostatic pressing under vacuum or protective atmosphere, and finally sintering and heat treatment. The nickel titanium alloy prepared by powder metallurgy method has high purity and density, making it suitable for manufacturing complex shaped components.
Melting method
The smelting method is to mix nickel and titanium in a certain proportion and then melt them, and then cast or roll them into shape. The nickel titanium alloy prepared by melting method has good processing performance and is suitable for manufacturing large components.
Electron beam evaporation method
Electron beam evaporation is a method for preparing ultra-thin nickel titanium alloy films. This method utilizes electron beam evaporation technology to evaporate nickel and titanium onto the substrate, followed by heat treatment and cooling crystallization. The nickel titanium alloy thin film prepared by electron beam evaporation method has high purity, high density, and good shape memory effect.
