“Gum metal”的意思、由来-开放百科全书

Applying cold work to gum metal actually decreases its elastic modulus,^[1] with reported shear moduli as low as {{convert|20|GPa|psi}}.^[3]

At the same time, cold work increases gum metal's yield strength.^[1] By using a heat treatment after this cold work, some elasticity can be sacrificed for even greater strength, with yield strengths ranging as high as {{convert|2|GPa|psi}}, on par with some of the strongest steels.^[3]

"Gum metal" is a registered trademark of Toyota Central R&D Labs and was initially developed there. The results of that research were first published in April 2003.^[3]
