(3) \u00c7atlak ve inkl\u00fczyon kusurlar\u0131n\u0131n giderilmesi \u00fczerinde etkisi yoktur.<\/p>

(4) S\u0131cak izostatik presleme par\u00e7an\u0131n y\u00fczeyinde oksitlenmeye neden olabilir ve tercihen finisaj i\u015flemleri aras\u0131nda ince bir oksit filmi olu\u015fturabilir.<\/p>

(5) S\u0131cak izostatik presleme par\u00e7ada ciddi bozulmalara neden olabilir ve bozulmay\u0131 \u00f6nleyecek tedbirler her zaman bu i\u015flemden \u00f6nce d\u00fc\u015f\u00fcn\u00fclmelidir.<\/p>
