The article is devoted to the compressive review of the defects observed in the products of the machinery usage made mainly of anti-corrosion steels of the martensite-austenite group, difficult to process materials such as pure titanium, nickel, and their alloys, super and high entropy alloys and triple fusions produced by laser additive manufacturing, particularly the laser powder bed fusion
Microwave (MW) application for heating was discovered in 1946 and has been applied in various fields. The detailed historical tracing is presented in the next section. Among the various aplications, it is possible to classify them into two major classes (Agrawal, 2005). In the first class, MW heating applied to drying, cooking foods and to excitation of chemical reactions such as inorganic/…
LT21 a type of aluminum alloy used for the irradiation channel of the first heavy water research reactor (HWRR) in China. Studying the mechanical property of irradiated LT21 aluminum under actual service conditions is essential for evaluating its application property. In this paper, tensile specimens of irradiated LT21 were manufactured from the decommissioned irradiation channel of an HWRR…
