A method of manufacturing high-zirconium getters that involves hydrogen pulverization of an entire alloy ingot or ingot pieces. The method offers distinct advantages over techniques that use mechanical means of powder production. The method is useful especially in the manufacture of tough porous getters, of high Zr-content Zr-V alloys that have minor additions of elements such as Fe, Ni, Mn and/or Al.

A strip getter structure comprising getter powder pressed into and onto an open reticulated network carrier strip. The getter powder particles form an agglomeration with strength derived both from interlocking of said getter particles and from support of the getter agglomeration by the network. The getter strip structure is manufactured by continuous rolling of getter powder into and onto the network carrier strip by means of a gravity powder feed and a cylindrical rolling mill.

A method for forming intermetallic and intermetallic-type precursor alloys for subsequent mechanical alloying applications. Elemental powders are blended in proportions approximately equal to their respective intermetallic compounds. Heating of the blend results in the formation of intermetallic compounds whereas lack of heating results in intermetallic-type powder without the intermetallic structure. The resultant powder is then blended to form a final alloy. Examples involving aluminum-titanium alloys are discussed.

A batch-type rotary grinding mill operable under seal to the atmosphere is provided with a discharge system which permits discharge of material from the mill under seal and without disturbing the seal in the mill. The discharge system comprises at least one discharge chute which is sealably secured to the shell wall, spiraling adjacent to the shell and traversing the shell wall from one end to the other. The material is discharged from the discharge chute via a hollow trunnion which, preferably, contains a conveyor to aid in passing the material out of the mill into an environmentally protected device.
