摘要
低温退火加拉伸是加速消除 TiAl 基合金中 B2 相的有效方法。拉伸应力能对原子产生径向压应力，并促进原子空位的形成，这两种应力都能促进原子扩散，从而加速 B2 相的消除。
Accelerated elimination of residual B2 phase in TiAl-based alloys by low-temperature annealing plus stretching
Low-temperature annealing plus stretching is an efficient method to accelerate the elimination of B2 phase in TiAl-based alloys. The stretching stress can produce radial compressive stress on atom and promote the formation of atomic vacancies, both of which promote the atom diffusion, thus accelerating the elimination of B2 phase.
期刊介绍：
Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences.
A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below.
The scope of the journal includes:
1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes).
2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis.
3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification.
4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
