Metals at low temperature
WebCertain metals (e.g., iron, titanium, and nickel) are more susceptible to HE than others (e.g., copper, aluminum, and austenitic stainless steel). Removal of the metal from the source of hydrogen and heat treatment (to about 200°C) restores its mechanical properties. Web14 apr. 2024 · High-strength, low-alloy (HSLA) steel has attracted much attention in the manufacturing industry because of its good combination of high strength and toughness, low cost, and good formability. Wire and arc additive manufacturing (WAAM) technology can realize the rapid prototyping of HSLA steel parts. This study investigated a 26-layer …

Web“It is perhaps unfortunate that so much attention has been paid to the resistance of metals, since it is probably one of the least characteristic properties of the substance, and … WebAt low temperatures some metals that would be ductile at room temperature become brittle. This is known as a ductile to brittle transition. The ductile to brittle transition temperature is strongly dependant on the composition of the metal. Steel is the most commonly used metal that shows this behaviour.
