| titleOfInvention | Lead-free-cutting brass containing metal hydride and preparation method thereof |
| abstract | A leadless free-cutting brass containing metal hydride and a preparation method thereof are characterized in that the brass contains 1-15 wt% of metal hydride. The preparation method comprises the following steps: and (3) absorbing hydrogen from the hydrogenatable alloy element in the alloy under certain hydrogen conditions to generate metal hydride, and finally obtaining the metal hydride-containing lead-free-cutting brass, wherein the raw material brass alloy contains at least one hydrogenatable alloy element which is required to form a uniform alloy or solid solution with the matrix alloy element. The preparation method of the leadless free-cutting brass containing the metal hydride can be used for large-scale production, and the obtained leadless free-cutting brass containing the metal hydride is suitable for the field of metal processing, and particularly improves the cutting processability of brass; the method has simple process and abundant required raw material reserves, and the obtained leadless free-cutting brass containing metal hydride has no pollution and meets the requirement of environmental protection. |
