Abstract

In this work a new understanding of built-up edge formation was developed by applying new methods. For the first time built-up edge formation was examined in-situ in a relevant cutting parameter range by radiographic and optical methods with high temporal resolution. Additionally sophisticated analytical techniques were applied for the ex-situ examination of the microstructure in the built-up edge. A correlation between built-up edge formation and tool wear was deduced.

Abstract

Friction stir welding (FSW) is considered to be the most significant development in metal joining in decades and, in addition, is a ""green"" technology due to its energy efficiency, environmental friendliness, and versatility. This process offers a number of advantages over conventional joining processes. Furthermore, because welding occurs via the deformation of material at temperatures below the melting temperature, many problems commonly associated with joining of dissimilar alloys can be avoided, and thus, high-quality welds are produced. Due to this fact, FSW has been widely used in different industrial applications where metallurgical characteristics should be retained, such as in the aeronautic, naval, and automotive industries.

Abstract

The papers collected in this special issue clearly reflect the modern research trends in materials science. These fields of specific attention are high-Mn TWIP steels, high-Cr heat resistant steels, aluminum alloys, ultrafine grained materials including those developed by severe plastic deformation, and high-entropy alloys. The major portion of the collected papers is focused on the mechanisms of microstructure evolution and the mechanical properties of metallic materials subjected to various thermo-mechanical, deformation or heat treatments. Another large portion of the studies is aimed on the elaboration of alloying design of advanced steels and alloys. The changes in phase content, transformation and particle precipitation and their effect on the properties are also broadly presented in this collection, including the microstructure/property changes caused by irradiation.
