Claims (6)

  1. 특히 군사무기용에서 철, 니켈 및 구리같은 금속원소를 첨가하여 얻어진 압축되고 소결된 텅스텐 합금의 블랭크를 가공경화하여 회전축을 갖게하고 적어도 17000kg/㎥의 밀도를 갖게하는 발사체의 성형방법에 있어서, 발사체를 일정한 형태로 만들고 사용중에 생기는 발사체의 응력에 국부적으로 적응하는 특성을 갖도록 하기 위하여 상기 적절한 형상의 미완성 블랭크가 블랭크의 축에 평행한 방향에서의 수축 정도에따라 상온과 500℃사이의 온도에서 가공 경화처리 되는 것을 특징으로 하는 발사체의 성형방법.
  2. 제1항에 있어서, 적절한 형태의 미완성 블랭크는 W-Ni-Fe와 W-Ni-Cu의 분말로 만들어진 것중에 속하는 분말 혼합물로부터 얻어지며, 주형속에서 압축되고 1400-1600℃의 수소 분위기에서 소결되는 것을 특징으로 하는 발사체의 성형방법.
  3. 제1항에 있어서, 적절한 형태의 미완성 블랭크는 W-Ni-Fe와 W-Ni-Cu의 분말로 만들어진 것중에 속하는 분말 혼합물로부터 얻어지며, 실린더 또는 평행육면체 같은 간단한 형상에 따라 주형속에 압축된후 기계가공되는 것을 특징으로 하는 발사체의 성형방법.
  4. 제1항 내지 제3항중 어느 한 항에 있어서, 블랭크축에 평행한 방향으로의 단면 수축율은 5%-60%인 것을 특징으로 하는 발사체의 성형방법.
  5. 제1항 내지 제4항중 어느 한 항에 있어서, 단면 감소에 의한 가공경화 처리는 회전햄머링 조작에 의하여 만들어지는 것을 특징으로 하는 발사체의 성형방법.
  6. 제5항에 있어서, 회전 햄머링 조작은 회전-교대 작용을 가지며 적어도 2개의 햄머로 구성된 성형 공구장치와 결합된 햄머링 장치에 의하여 이루어지는 것을 특징으로 하는 발사체의 성형방법.
