Abstract

One of the most critical issues affecting tungsten (W) as plasma facing material is ductile-to-brittle transition behavior. It is well known that the microstructure of W materials is influenced by the fabrication methods and histories, which can affect those behaviors. In this paper. the current status of Charpy impact properties (ductile-to-brittle transition temperature (DBTT) etc.) of pure and modified W materials fabricated by several methods and histories are reviewed based on the open literatures and the possibility of integrated interpretation of Charpy impact properties of W materials from different production routes is discussed.
