Process for creating high strength tubing with isotropic mechanical properties. |
摘要 |
<p>High strength alloy steel cartridge cases characterized by very high isotropic yield strength characteristics are produced from high temperature austenitic conditioned materials by subjecting the materials to a substantial one-pass draw operation and thereafter freezing the materials at approximately -100<o>F prior to age hardening. <IMAGE></p> |
