Additive manufacturing technologies based on melting and solidification have considerable
similarities with fusion-based welding technologies, either by electric arc or high-power …

Ultrasonic processing has attracted increasing attention by people because ultrasonic
technology may represent a flexible 'green'alternative for energy efficient processes. The …

Additive manufacturing (AM) of metals, also known as metal 3D printing, typically leads to
the formation of columnar grain structures along the build direction in most as-built metals …

One of the less desirable aspects of fusion-based additive manufacturing is the propensity
for coarse columnar grain structures crossing build layers to form. This paper initially …

This review paper aims to introduce systematic in-depth analysis of diversified aspects of
ultrasonic application in metal joining and processing including its limitations, future …

In recent years, ultrasonic technology has been extensively applied in numerous
manufacturing processes to improve the process performance and part quality. This review …

Joining processes especially for metallic materials play critical roles in manufacturing
industries and structural applications, therefore they are essential to human life. As a more …
